OnlyFans
OnlyFans is a subscription-based content-sharing platform launched in 2016, enabling creators to monetize exclusive digital content such as videos, photos, and live streams directly from subscribers.[1] Founded by British entrepreneur Tim Stokely, who drew from prior experience in adult-oriented sites like Customs4U, the platform was initially seeded with £10,000 from his father, Guy Stokely.[2] In 2018, Ukrainian-American investor Leonid Radvinsky, owner of adult webcam site MyFreeCams, acquired a majority stake, transforming it into a major player in online content monetization.[3] Stokely stepped down as CEO in December 2021, succeeded by Amrapali Gan, who had joined in 2020.[4]
The platform's business model allows creators to set monthly subscription fees typically ranging from $4.99 to $49.99, retaining 80% of gross payments while OnlyFans takes a 20% commission; additional revenue comes from pay-per-view messages, tips, and custom content requests.[5] Although marketed for diverse categories including fitness, music, and cooking, empirical data indicates that over 80% of content is sexually explicit, driving the majority of its $7.22 billion gross revenue in fiscal year 2024, a 9% increase from prior years, with pre-tax profits of $684 million.[6] As of February 2025, OnlyFans reported over 51.47 million registered users and approximately 4.11 million active creators worldwide, reflecting a 22% user growth from the previous year amid sustained pandemic-era demand surges.[7][8]
OnlyFans gained prominence during the COVID-19 lockdowns starting in 2020, as traditional income sources evaporated for many, leading to a 540% revenue jump to $400 million in the year ending November 2020; high-profile entrants like celebrities and athletes further boosted visibility, though the core user base remains tied to adult content consumption.[9] Controversies persist, including 2021's aborted policy to ban sexually explicit material under pressure from banking partners, which was reversed due to creator backlash, highlighting tensions between financial intermediaries and platform operations.[5] Critics, including reports from outlets like The New York Times, argue the model facilitates indirect management of sex work by agencies acting as "e-pimps," potentially exploiting vulnerable creators through revenue splits and content control, while proponents cite direct payouts—averaging significant earnings for top performers—as evidence of economic agency in a digital economy.[10] Empirical analyses underscore risks of content piracy, privacy breaches, and psychological tolls on participants, with leaked material proliferating despite platform safeguards.[11]
Sports
Old Firm
The Old Firm refers to the intense football rivalry between Celtic Football Club and Rangers Football Club, two Glasgow-based teams that have dominated Scottish football since the late 19th century. The term originated in the early 1900s, likely from a 1904 match report describing the clubs as "two old, firm friends" in competition, or from their joint economic influence on the Scottish game, where matches between them generate significant revenue despite underlying tensions. The first encounter occurred on 28 February 1888, with Celtic defeating Rangers 5–2 in a friendly at Celtic Park, then known as Parkhead.[12][13]
Celtic was founded in 1887 by Brother Walfrid, an Irish Marist Brother, to raise funds for the impoverished Irish Catholic immigrant community in Glasgow's East End amid the potato famine's aftermath and industrial migration. Rangers, established in 1872 by Protestant shipyard workers, drew support from the Protestant working class, reflecting broader ethnic and religious divides imported from Ireland's Catholic-Protestant conflicts and Scotland's own Reformation-era tensions. This sectarian underpinning—Celtic symbolizing Irish Catholic nationalism and Rangers embodying Ulster Protestant loyalism and British unionism—fueled the rivalry, with fanbases historically segregated by faith, leading to discriminatory practices like Rangers' unwritten policy against signing Catholic players until 1989.[14][15]
As of 2024, the clubs have contested over 430 matches, with Rangers holding a slight historical edge: 171 wins to Celtic's 170, alongside 89 draws. In league fixtures since 1891, Rangers lead with 127 victories to Celtic's 114, and 90 draws, though Celtic has won 10 of the last 15 Old Firm derbies as of 2023. The rivalry's stakes extend beyond sport, often deciding Scottish Premiership titles—Rangers secured 55 league championships to Celtic's 53 by 2024—and influencing European qualifications, with both clubs amassing 1 European Cup/Champions League final appearance each (Celtic winning in 1967).[16][17][18]
Sectarianism has manifested in violence, with Old Firm games linked to public disorder, hooliganism, and fatalities; estimates attribute 8–15 murders to rivalry-related incidents since 1909. Police data from Strathclyde (2008–2011) recorded a statistically significant spike in domestic violence reports—up to 37% higher—on days following matches, correlating with alcohol-fueled aggression rather than direct game outcomes. Efforts to mitigate include UEFA-mandated alcohol bans in stadiums since 1994 and Scotland's Offensive Behaviour at Football and Threatening Communications Act (2012–2018), which targeted sectarian chants but was repealed amid free speech concerns. Despite declining overt religiosity—only 18% of Scots identify as Protestant or Catholic per 2011 census—the divide persists in symbols like Celtic's Irish tricolour flags and Rangers' union jacks.[13][19][20]
Language and linguistics
Old French
Old French designates the set of Gallo-Romance dialects spoken primarily in northern France from the 9th to the 13th century.[21] These varieties emerged as daughter languages of Vulgar Latin, following the Roman conquest and Romanization of Gaul beginning in 121 BC and continuing through the 5th century AD, with substrate influences from Gaulish Celtic languages and superstrate effects from Frankish Germanic during the early medieval period.[21] The language shifted from Latin's typical subject-object-verb order toward subject-verb-object as a dominant structure.[21]
The earliest attested text in a distinctly Gallo-Romance vernacular is the Serments de Strasbourg (Oaths of Strasbourg) from 842 AD, recording oaths sworn by Carolingian rulers in a form separating from both Latin and Old High German.[21] [22] Old French comprised a dialect continuum rather than a standardized tongue, centered on the langue d'oïl (from the affirmative oïl for "yes"), which included Francien (spoken around Île-de-France and serving as the basis for modern standard French), Picard (northern, with Flemish contacts), Norman (northwestern, influenced by Norse via Viking settlements), and others like Champenois and Walloon.[21] Distinct from the southern langue d'oc (Occitan varieties using òc for "yes"), langue d'oïl dialects showed mutual intelligibility but regional phonological divergences, such as varying negation reinforcers (pas in some areas, mie in others).[21]
Phonologically, Old French retained a complex Latin-derived vowel inventory, including diphthongs like /ei/ and /ou/, alongside monophthongs, with consonants undergoing palatalization (e.g., Latin /k/ before front vowels becoming /ts/ or /s/).[21] Morphologically, it preserved a simplified case system for nouns—primarily nominative versus oblique—inflected for gender (masculine/feminine) and number (singular/plural), while adjectives agreed accordingly; pronouns and articles (an innovation over Latin, with definite forms tracing to Latin demonstratives) followed suit.[21] Verbal morphology remained rich, conjugating for person, number, tense (present, imperfect, future via periphrasis), mood (indicative, subjunctive, imperative), and voice (active, passive via se constructions).[21]
Syntactically, sentences favored subject-verb-object order, but flexibility persisted: subject inversion after certain adverbs or in questions was routine, and subordinate clauses often employed subject-object-verb.[21] Preverbal clitics for objects and negation particles preceded finite verbs, contributing to a topic-prominent structure in narrative prose.
Old French literature flourished in oral-derived forms committed to writing, including chansons de geste (epic songs) like La Chanson de Roland (c. 1100–1120), an assonant 4,000-line poem depicting Charlemagne's nephew Roland's death at the Battle of Roncevaux Pass in 778 AD, emphasizing feudal loyalty and Christian warfare.[23] Other genres encompassed courtly romances (roman), saints' lives (vies), and lyric poetry in forms like the pastourelle.[21]
The period ended around the late 13th century, transitioning to Middle French (roughly 14th–17th centuries) amid nasalization of vowels, reduction of diphthongs, progressive case loss (full merger to oblique by 1300 in Francien), and syntactic rigidification toward modern SVO norms, driven by Parisian administrative dominance post-Capetian consolidation.[21]
Places
Of, Norway
Of is a small rural locality and farm area in Grue municipality, Innlandet county, Norway, situated in the traditional Solør district along the Glomma river valley. The surrounding region features flat agricultural land interspersed with forests, supporting farming and forestry as primary economic activities.[24] Grue municipality, which encompasses Of, covers 837 square kilometers and had a population of 4,513 as of January 2023, with low population density of 5.4 inhabitants per square kilometer indicative of sparse rural settlements like Of.[25] The area is part of the Finnskog borderlands historically influenced by Finnish immigrants, though specific records for Of itself are limited to local parish and farm registers dating back to the 17th century.[26] No major historical events or notable structures are associated with Of, reflecting its status as a typical minor farm community in eastern Norway's inland landscape.
Post-nominals and titles
Officer designations
In the NATO military rank system, "OF" designates commissioned officer grades, standardized under STANAG 2116 (NATO Codes for Grades of Military Personnel) to facilitate interoperability and comparison across member nations' armed forces.[27] This coding scheme assigns numerical values from OF-1 (entry-level officers) to OF-10 (supreme command ranks), reflecting hierarchical equivalence rather than identical titles or insignia, which vary by country and service branch.[28] The system excludes warrant officers (coded WO) and enlisted personnel (coded OR), focusing solely on commissioned officers who hold presidential or equivalent commissions.[29]
OF codes enable precise personnel accounting, joint operations planning, and rank equivalence in multinational contexts, such as NATO exercises or coalitions. For instance, OF-1 typically corresponds to sub-lieutenant or second lieutenant equivalents, while OF-5 aligns with lieutenant colonel or commander levels.[30] Implementation began with the agreement's ratification in the late 1970s, with updates to accommodate evolving national structures, though core equivalences remain consistent as of the latest editions.[31]
The following table outlines standard OF designations with representative ranks in army, navy, and air force contexts, drawn from NATO harmonization:
| OF Code | Army Example | Navy Example | Air Force Example |
|---|
| OF-1 | Second Lieutenant | Ensign/Midshipman | Pilot Officer |
| OF-2 | First Lieutenant/Captain | Lieutenant Junior Grade | Flying Officer |
| OF-3 | Captain | Lieutenant | Flight Lieutenant |
| OF-4 | Major | Lieutenant Commander | Squadron Leader |
| OF-5 | Lieutenant Colonel | Commander | Wing Commander |
| OF-6 | Colonel | Captain | Group Captain |
| OF-7 | Brigadier General | Rear Admiral (Lower Half) | Brigadier General |
| OF-8 | Major General | Rear Admiral (Upper Half) | Major General |
| OF-9 | Lieutenant General | Vice Admiral | Lieutenant General |
| OF-10 | General/Field Marshal | Admiral | Air Chief Marshal |
Science, technology, and engineering
Optical fiber
Optical fiber consists of a flexible, transparent strand of glass or plastic that transmits light signals via total internal reflection, enabling high-speed data communication over long distances.[32] The basic structure includes a central core of higher refractive index material surrounded by a cladding of lower refractive index, which confines the light within the core; an outer protective buffer coating is applied for mechanical durability.[33] Light propagation relies on the principle of total internal reflection, where light rays entering the core at angles greater than the critical angle are reflected back into the core rather than refracting out, minimizing signal loss.[34]
The theoretical foundation for practical optical fiber communication was established in 1966 by Charles K. Kao and George A. Hockham, who demonstrated that high signal attenuation in existing glass fibers resulted from impurities rather than inherent material limitations, proposing that ultra-pure glass could achieve losses low enough for telecommunications use.[35] Kao's work, which earned him the Nobel Prize in Physics in 2009, envisioned fibers transmitting light over kilometers when combined with laser sources.[36] Practical low-loss fibers were first produced in 1970 by Corning Incorporated, achieving attenuation below 20 dB/km at 632 nm wavelength through improved purification techniques.[37]
Two primary types dominate applications: single-mode fiber, with a core diameter of approximately 8-9 μm, supports only one light propagation mode using laser sources for minimal dispersion and transmission distances up to hundreds of kilometers; multi-mode fiber, featuring larger cores of 50 or 62.5 μm, accommodates multiple modes via LED or VCSEL sources but suffers higher modal dispersion, limiting distances to a few kilometers.[38] Single-mode is suited for long-haul telecommunications, while multi-mode serves shorter links like data centers or LANs.[39]
Manufacturing begins with creating a preform—a solid glass rod—via methods such as modified chemical vapor deposition (MCVD), where silica is deposited inside a rotating tube and collapsed into a preform, or outside vapor deposition (OVD), involving soot deposition on a bait rod.[40] The preform is then heated to around 2000°C in a drawing tower and pulled into a thin fiber at speeds up to 20 m/s, followed by application of polymer coatings for protection and testing for diameter uniformity and attenuation.[41]
In telecommunications, optical fibers underpin global networks by enabling terabit-per-second data rates over submarine cables and metro systems, far exceeding copper's capacity due to light's higher frequency and lower loss—typically 0.2 dB/km at 1550 nm versus copper's electrical resistance and electromagnetic interference susceptibility.[42] Advantages include bandwidths exceeding 100 Tbps in dense wavelength-division multiplexing systems, immunity to electrical noise, reduced signal attenuation over distances up to 100 km without repeaters, and lighter, thinner cables that facilitate easier installation in constrained spaces.[43] These properties have driven adoption in internet backbones, replacing copper for higher reliability and scalability in 5G and data-intensive applications.[44]
OpenFlow
OpenFlow is a communications protocol designed to enable software-defined networking (SDN) by providing a standardized southbound interface between a centralized controller and network forwarding devices, such as switches and routers. It allows the controller to install, modify, and remove flow rules that dictate packet forwarding decisions based on header fields, thereby decoupling the control plane from the data plane.[45] The protocol operates over secure channels, typically using TCP on port 6653 or TLS, and supports features like flow statistics querying, port configuration, and group table management for more complex forwarding behaviors.[46]
Development of OpenFlow originated in 2006 at Stanford University, where PhD student Martin Casado, along with professors Nick McKeown and Scott Shenker, sought to enable programmable networks by exposing switch internals to external software.[47] Initial prototypes demonstrated the feasibility of remote flow table programming, leading to the first OpenFlow specification version 1.0 released in December 2009.[48] The Open Networking Foundation (ONF), established on March 22, 2011, by companies including Google, Facebook, and Cisco, took over standardization to promote interoperability and vendor adoption.[49]
Technically, OpenFlow defines a binary protocol with message types including controller-to-switch (e.g., FlowMod for rule installation), asynchronous (e.g., PacketIn for unknown flows), and symmetric (e.g., Echo for keep-alives). Flow tables match packets on fields like Ethernet source/destination, IP addresses, TCP/UDP ports, and VLAN tags, with actions such as output to ports, modify headers, or drop.[50] Later versions introduced enhancements like multiple tables for pipelined processing (version 1.1, February 2011), extensible match (version 1.2, December 2011), and support for optical ports and metering (version 1.5, March 2015).[48] By 2014, OpenFlow had evolved to address limitations in early versions, such as rigid matching, through vendor extensions and ONF refinements, though adoption shifted toward hybrid models integrating with traditional protocols.[49]
Adoption of OpenFlow accelerated in data centers and campus networks for its programmability, with implementations in open-source platforms like Open vSwitch and commercial hardware from vendors including Cisco, Juniper, and Huawei.[51] However, challenges include scalability for large networks, where controller bottlenecks arise, and security risks from centralized control, prompting hybrid deployments combining OpenFlow with legacy protocols.[52] As of 2023, OpenFlow remains foundational to SDN but has been supplemented by protocols like NETCONF and P4 for greater flexibility in programmable data planes.[53]
Overflow (computing)
In computing, arithmetic overflow occurs when a numerical computation produces a result that exceeds the maximum or minimum value representable by the data type's allocated bits, leading to wraparound or undefined behavior depending on the system.[54] This phenomenon arises primarily in fixed-precision representations such as integers and floating-point numbers, where the finite bit width imposes strict bounds on storable values. For instance, in binary addition, overflow is detected if the carry into the sign bit differs from the carry out of it, signaling a result outside the signed range.[55] Processors often provide overflow flags in their status registers to indicate such conditions, enabling software to check and handle them explicitly.[56]
Integer overflow, a common subtype, happens when an arithmetic operation on integers yields a value beyond the type's range, typically wrapping around in two's complement systems. For a 32-bit signed integer, the range spans from -2,147,483,648 to 2,147,483,647; adding 1 to the maximum value results in -2,147,483,648 due to wraparound.[55] Unsigned integers wrap modulo 2^n, where n is the bit width, producing predictable but incorrect results like 4,294,967,295 + 1 equaling 0 in 32 bits. Causes include accumulation of values exceeding limits, as in loops or repeated additions, or inadequate type sizing for expected inputs.[57] Such overflows can propagate errors in algorithms, for example, causing incorrect loop terminations or financial miscalculations, and pose security risks by enabling buffer overruns when sizes are computed from overflowed values.[58] Historical vulnerabilities include the 1996 Ariane 5 rocket failure, where a 64-bit float converted to 16-bit unsigned integer overflowed during velocity computation, triggering self-destruct 37 seconds after launch.[58]
c
int32_t a = 2147483647; // INT_MAX for 32-bit signed
int32_t b = a + 1; // Overflows to -2147483648
int32_t a = 2147483647; // INT_MAX for 32-bit signed
int32_t b = a + 1; // Overflows to -2147483648
In languages like C, behavior is implementation-defined without explicit checks, though compilers may optimize away detectable overflows under certain flags.[59] Mitigation strategies involve selecting wider types (e.g., int64_t over int32_t), employing checked arithmetic libraries like those in Java's BigInteger or C#'s checked contexts, or validating inputs pre-operation. Static analysis tools and compiler warnings, such as GCC's -ftrapv for trapping on overflow, further aid prevention.[54]
Floating-point overflow, governed by standards like IEEE 754-1985 (revised in 2008 and 2019), occurs when the result's magnitude surpasses the maximum representable value, typically yielding positive or negative infinity while setting an overflow flag.[60] In double-precision (64-bit) format, the exponent range allows values up to approximately 1.8 × 10^308; exceeding this during multiplication or exponentiation triggers infinity.[61] Unlike integer wraparound, IEEE 754 mandates signaling via exceptions or flags, with options for trapping to handlers or continuing with infinity, which propagates in further operations (e.g., inf + finite = inf).[62] Underflow, the counterpart for subnormal results, contrasts by denormalizing or flushing to zero, but overflow rarely causes wraparound, preserving partial information through infinity semantics. Applications in scientific computing must handle these via scaled computations or arbitrary-precision libraries to avoid cascading errors.[63]
Organizations and institutions
Ofcom
The Office of Communications (Ofcom) is the independent regulator and competition authority for the United Kingdom's communications industries, overseeing television, radio, fixed-line telecommunications, mobile services, broadband, postal services, and the spectrum used for wireless communications.[64] Established on 29 December 2003 under the Office of Communications Act 2002 and the Communications Act 2003, Ofcom consolidated the functions of five predecessor bodies: the Independent Television Commission (ITC), Office of Telecommunications (Oftel), Radio Authority, Radiocommunications Agency, and parts of the Broadcasting Standards Commission.[65] This merger aimed to streamline regulation amid converging technologies, with initial setup costs exceeding £56 million funded by a government loan.[66]
Ofcom's principal statutory duties, as outlined in the Communications Act 2003, require it to further the interests of UK citizens in media content and spectrum use, while promoting competition and protecting consumers in relevant markets through measures such as licensing, spectrum auctions, and enforcement of quality standards.[67] In broadcasting, it enforces codes on accuracy, impartiality, harm, and offence, assessing public complaints—receiving over 100,000 annually in recent years—and imposing sanctions like fines or license revocations when breaches occur.[68] For telecommunications, it promotes infrastructure investment, resolves disputes between providers, and ensures service reliability, including oversight of the Universal Service Obligation for broadband access.[69]
Under the Online Safety Act 2023, effective from 2025, Ofcom gained expanded powers to regulate online platforms for illegal and harmful content, including requirements for risk assessments, content removal, and age verification; non-compliance can result in fines up to 10% of a firm's global annual turnover or £18 million, whichever is greater, alongside potential criminal offenses for executives.[70] [71] Enforcement actions have included multimillion-pound penalties against broadcasters for serious breaches, such as ITV's £18 million fine in 2019 for misleading viewers during a giveaway promotion.[72]
Ofcom has faced criticism for perceived inconsistencies in applying impartiality rules, particularly in politically charged cases. Conservative-leaning outlets have accused it of overzealous scrutiny against channels like GB News, which received multiple investigations for politician-presenter ratios and opinion-led content, leading to upheld breaches in 2023 and 2024.[73] Conversely, progressive campaigners have claimed leniency, alleging Ofcom permits climate skepticism on GB News and others in violation of accuracy standards, as highlighted in a 2025 complaint coalition arguing for stricter enforcement against denialism.[74] Such disputes reflect broader debates on regulatory capture and institutional bias, with Ofcom's decisions often contested amid polarized media landscapes where left-leaning mainstream sources dominate complaint volumes on right-leaning outlets.[75]
Other organizations
OnlyFans, frequently abbreviated as OF in digital communications and social media, is a London-based online platform founded on November 1, 2016, by entrepreneur Tim Stokely. The service operates as a subscription-based content-sharing site where creators, including models, influencers, and adult entertainers, can monetize videos, photos, and live streams through fan payments, with the company taking a 20% commission on earnings. By 2021, it reported over 2 million creators and 190 million users, generating $5 billion in creator payouts amid a surge in popularity during the COVID-19 lockdowns that restricted traditional income sources for many sex workers and performers. The platform briefly attempted to prohibit sexually explicit content in August 2021 due to payment processor pressures but reversed the policy within days following backlash from creators reliant on adult material, which constitutes the majority of its revenue.
While not officially branded as "OF," the abbreviation has become widespread in online shorthand, particularly on platforms like TikTok and Twitter, where it refers to the service's role in enabling direct fan-creator interactions often involving erotic or personalized content. Critics, including some financial analysts, have noted risks from its heavy dependence on adult content amid evolving banking regulations and app store policies, though it has expanded into fitness, music, and cooking niches. As of 2023, OnlyFans' parent company, Fenix International Limited, achieved unicorn status with a valuation exceeding $1 billion, underscoring its commercial success despite ethical debates over exploitation and content moderation.
Modern internet slang
In contemporary online discourse, particularly on social media platforms such as TikTok and Instagram, "OF" functions as a shorthand abbreviation for OnlyFans, a subscription-based content platform launched in November 2016 by British entrepreneur Tim Stokely.[76][77] The term gained traction amid the platform's rapid growth during the COVID-19 pandemic, when user numbers surged from approximately 20 million in 2019 to over 85 million registered users by 2021, driven largely by creators monetizing exclusive material.[78] While OnlyFans permits diverse content including fitness tutorials, cooking videos, and music, empirical estimates indicate that 70-80% of its material is adult-oriented or pornographic, shaping the slang's connotations toward sex work and explicit subscriptions.[78][79]
The abbreviation "OF" is frequently deployed to circumvent platform algorithms that flag or restrict direct promotions of adult services, allowing creators to subtly advertise profiles—e.g., phrases like "link in bio for OF" or "starting my OF journey"—without immediate content removal.[76][80] This usage reflects broader patterns in internet vernacular where brevity and evasion of moderation foster coded language, especially in communities centered on influencer economies and fan interactions. On forums like Reddit, "OF" often denotes creators' earnings potential, with top performers reporting millions in annual revenue, though median creator income remains low at around $180 per month as of 2023 data.[80][78]
Critics, including parental monitoring organizations, highlight "OF" as a euphemism signaling involvement in sex work, underscoring its association with platforms where subscribers—predominantly male, comprising 70-80% of paying users—access personalized adult content via tiered paywalls starting at $4.99 monthly.[81][82] The slang's prevalence has prompted secondary codes, such as "accountant" for OnlyFans creators seeking discretion in professional contexts, illustrating adaptive linguistic strategies in digital economies reliant on explicit content.[81] Despite OnlyFans' 2021 brief ban on pornography (later reversed due to backlash), the term "OF" persists as a neutral yet loaded marker of the platform's cultural footprint in Gen Z and millennial online spaces.[78]
Traditional slang
"OF" serves as an abbreviation for "old fart" in informal communication, particularly in early internet chat rooms, texting, and acronym lists from the late 20th and early 21st centuries.[83] This usage predates widespread social media platforms and contrasts with more recent interpretations, positioning it within traditional digital slang rather than contemporary trends. The term "old fart" itself denotes an elderly individual, typically implying traits such as stubbornness, grumpiness, or resistance to change, and carries a mildly derogatory or humorous tone depending on context.[84]
The full phrase "old fart" emerged in British and American English slang by the 1840s, with Dictionary.com recording its initial appearances between 1840 and 1845, often evoking imagery of flatulence associated with aging bodies to underscore perceived obsolescence or eccentricity.[84] By the 1990s and 2000s, as online forums and instant messaging proliferated, abbreviations like "OF" condensed such expressions for brevity in typed conversations, appearing in glossaries aimed at decoding youth or online lingo for adults.[83] User-generated resources, such as Urban Dictionary entries from the mid-2000s onward, further documented "OF" in this sense, reinforcing its niche but persistent role in casual discourse among English speakers.[85] While not as ubiquitous as acronyms like "LOL" or "BRB," it reflects a pattern of abbreviating age-related idioms in pre-smartphone digital etiquette.
