Chief Wiggum: Uh, why don't you talk to that officer over there? I'm going out to lunch.
The Simpsons, "Duffless"

Characters get their acronyms confused, often involving mistaking one for another, and/or misremembering an acronym severely enough to intend to refer to one acronym, but actually mention another.

Subcategories include acronyms being confused due to sharing an initialism, and acronyms getting mixed up for other reasons.

The whole book consists of the two knights performing all kinds of whacky hijinks to impress him (all the while hiding the fact, that most people in town have been cursed with sloth) only to find out that... he wasn't quite so important. The acronym was the same... N.I.K. (Which in Poland is Najwyższa Izba Kontroli (Supreme Chamber of Control) but here interpreted as Najwyższa Inspekcja Kaszteli (Highest Inspector of Castles). Turned out to be Niższy Instruktor Konkursów (Junior Instructor of Competitions)).

  • In National Security, Earl (Martin Lawrence) spots a file in Da Chief's office labelled "CIA Heist". Hank (Steve Zahn) assumes Earl is making this up. Later, though, they find that the bad guys have been raiding warehouses for kegs made of a new space-age alloy worth millions. They confront Da Chief with it, who confirms the CIA connection. Hank is incredulous, assuming they're talking about the Central Intelligence Agency. Both Earl and Da Chief look at him like he's an idiot and explain that they mean Crupps International Aerospace. Earl later asks why Hank thought he meant the actual CIA.
  • In the Woody Allen film Bananas, the dictator of San Marcos discusses the possibility of a rebel overthrow:

  • For some reason, a character from R.O.T.O.R. uses "C.O.D."note  as a Bond One-Liner, even though it makes no sense in context. One would surmise they had intended "D.O.A."note

  • There's an old one about a genteel woman inquiring about toilet facilities at a campground - she even found her euphemism 'bathroom commode' too vulgar and shortened it to 'B.C.' which causes some confusion.

  • Dies The Fire. An ex-recon Marine is asked post-coitus about a scar he got during Desert Storm. He says it's from an RPG, causing the puzzled woman to wonder how you get a scar during a Role-Playing Game.
  • In The Laundry Files by Charles Stross, the organisations formerly known as MI5 and MI6 have invoked and exploited Acronym Confusion by changing their initialisms to DI5 and DI6 respectively and having their old initalisms reassigned. This way, the government can honestly claim that MI5 is certainly not doing whatever Orwellian thing they're being accused of while forgetting to explain that this is because MI5 is the organisation in charge of rubbish collection.

  • In the Get Smart episode "A Man Called Smart", Max is looking for someone known only as 'T.B.O.'. While standing at a catering truck, this exchange occurs:
    Maxwell Smart: Bediyoskin told us to contact you. He even wrote your initials on a slip of paper. T.B.O.
    Tom Orlando: T.B.O. can mean a lot of things.
    Maxwell Smart: Oh really? For instance, give me another T.B.O.

    Maxwell Smart: T.B.O.?
    Caterer: Tomato and bacon on an onion roll.

  • Given an extra-confusing twist in one of the "Get Me Hennimore!" sketches in That Mitchell and Webb Look - the hapless Hennimore has to look after two different groups, the Murder In The Dark (MITD) club, and a wine-tasting day for a charity for nervous incontinents (Nervous Incontinents Tasting Day - NITD), while simultaneously having to deal with a printing press that keeps switching Ns for Ms. What a mightnare.
  • In The Big Bang Theory episode "The Bat Jar Conjecture," Sheldon decides to name the team "Army Ants" due to the insects' strength. He even gets team T-shirts, which have "AA" written on them.

There's also Raj, Leonard, Howard, and Leslie's team, "Perpetual Motion Squad" or "PMS" for short.
  • In the Gilmore Girls episode "In the Clamor of the Clangor", Lorelai says that Luke should be working for the CIA because he's so inscrutable.

  • Dilbert:
    The VC are sick of BNB
    The Viet Cong are sick of breakfast in bed?

    Professional Wrestling 
  • Unfortunately common. On top of the International Wrestling Association, a group of territories banded together to compete against the National Wrestling Alliance, being in a few different countries as IWA, and another International Wrestling Association, a collaboration between promoters in Puerto Rico and Japan, there is also and Independent Wrestling Association and an Independent Wrestling Alliance, so if you get fans from different regions together, throwing around IWA without context is liable to confuse them. Occasionally promotions in the same country will have the same acronym, such as Ultimate Pro Wrestling and United Pro Wrestling in the USA (though they were on opposite sides of the country), Pure Wrestling Association and Prairie Wrestling Association in Canada. Then there are unfortunate cases such as Warriors Of Wrestling, a program from the 1990s and Women Of Wrestling, a program from 2001, which both got revivals around the same time, meaning there were two WOWs at once. The National Wrestling Alliance itself was preceded by the National Wrestling Association, which went out of business one year after the Alliance was founded but whose Midwest Tag Team titles were defended on the independent circuit as late as 2013.
  • The Chicago based Windy City Wrestling changed its name in 1997 to Windy City Pro Wrestling as World Championship Wrestling had really taken off the previous year and continued to.

  • In one stand-up routine, Dara Ó Briain talks about when he and his wife attended a pre-natal class while she was pregnant. Dara comments that such classes in England are run by the NCT, or National Childbirth Trust. He then points out that in Ireland NCT stands for "National Car Test".
    ''I, like a fuckin' idiot, forgot that, and walked out at the start of this tour saying, "Well I took my pregnant wife in for an NCT," and the whole room recoiled in horror, as if to go, "Why would you do that? Why would you take her into a garage and say, 'Jaysus, the handling is gone, she's all over the road! Mind you, the headlamps, the headlamps are better than I've ever seen them, don't touch them!'"'

  • A variation in The Pandora Directive. When kidnapped by the guys who introduce themselves as the NSA, Tex knows they're not talking about the National Security Agency but by the National Surveillance Agency.

    Web Original 

    Web Video 
  • Trent Hamilton got the meaning of USSR wrong when discussing a Soviet Cornet (he thought it stood for United States of Soviet Russia). In a second video, he apologized, and said USSR stood for the United Stitching and Sewing Ring, the Underground Society of Secret Rhythm, Uninterrupted Silent Sustained Reading, or the Union of Soviet Socialist Republics—whichever the watcher liked best.

    Western Animation 
  • The "Cartman Joins NAMBLA" episode of South Park involves confusion between the North American Man/Boy Love Association and the Nation Association of Marlon Brando Look-Alikes. The latter have a grudge towards the former since they managed to grab the "" domain first.

    • A tragedy of Shoehorned First Letter with the Krusty Komedy Klassic, made worse by the fact that that particular show was being held at the Apollo Theatre:
      Krusty: ...KKK?! That's not good!
    • In an episode where Bart makes a deal with some Chinese spies and gets stalked by a CIA (Central Intelligence Agency) van... which turns out to stand for the Chinese Intelligence Agency instead, who congratulate him for giving them information about the Springfield Nuclear Power Plant.

    • In "Duffless":
      Chief Wiggum: Uh, Mrs. Simpson, I have some bad news. Your husband was found DOA.
      Marge: Oh my god! He's dead?
      Chief Wiggum: Oh wait, I mean DWI. I always get those two mixed up.
      [Mrs. Phillips walks in.]
      Mrs. Phillips: My name's Mrs. Phillips. You said my husband is DWI?
      Chief Wiggum: Uh, why don't you talk to that officer over there? I'm going out to lunch.
  • From the "Zoobotnik" episode of Adventures of Sonic the Hedgehog:
    Coconuts: I only wanted to tell you I saw one of those F.O.U.s - I mean, C.I.A.s, uh, or C.O.D.s...
    Robotnik: Get to the point or your name will be M.U.D!
  • In the Phineas and Ferb episode "Just Our Luck", Candace celebrates that she's finally gotten a PHD - Perfect Hair Day. Her dad likewise has one for Pillow Hurtling Dexterity.
  • In one episode of Pinky and the Brain, when the duo commandeer a submarine, Brain has Pinky alter the acronym signal it gives out so no one will know it has been stolen. Pinky therefore changes the signal to say N.A.R.F. Unfortunately, the Pentagon thinks it stands for Nuclear Attack Readiness Formation and has the sub bombed with depth charges.

    Real Life 
  • A.A. can stand for Alcoholics Anonymous. Or you could be talking about the Argentium Astrum, a magical order founded by Aleister Crowley. The latter is spelled A∴A∴ for some mystical reason, or to avoid the confusion — take your pick.
    • In the UK AA can also stand for the Automobile Association, a motorists' club. Conversely, in America, AAA means American Automobile Association—or Anti-Aircraft Artillery, or the Archives of American Art.
  • There are currently three TV networks called ABC: the commercial American Broadcasting Company, the government-funded Australian Broadcasting Corporation, and Asahi Broadcasting Corporation, which serves in the Kansai region of Japan. There's also the former ITV station Associated British Corporation.
  • In game-related contexts, AC will be mostly associated with Assassin's Creed. Or the term "Armor Class". Nintendo fans, however, may think of Animal Crossing or Astral Chain. Some FROM Software fans may think of Armored Core. Some Namco fans may think of Ace Combat. And Final Fantasy fans may think of Advent Children. It can also stand for "Altador Cup", a major annual event on the online game Neopets. In Japan, "AC" literally stands for "arcade cabinet" and is used to refer to arcade games. Outside the context of gaming, AC can also stand for "alternating current" and "air conditioning".
  • There's potential transatlantic confusion with A&E: in the US, Arts and Entertainment Network; in the UK, (Hospital) Accident and Emergency department. If a British visitor to America asks for A&E, you'd better assume they're not looking for the network.
  • AU: an acronym for Gold (Aurum), Australia, or fanspeak for Alternate Universe? Jokes have been made about an alternate Australia being made out of gold, but one can still never be too sure.
  • BBC: A set of British state-owned TV networks, including a news channel, or a porn acronym for "Big Black Cock". Of course, many jokes have been been made at the expense of the British Broadcasting Corporation by its detractors for this.
  • You like to play BB? Why not, Bloodborne is a critical and commercial success so far. Wait, you were talking about BlazBlue? Or, who knows, maybe Bubble Bobble?
  • BLM: "Bureau of Land Management" or "Black Lives Matter"? The former manages the land for 1/8 of the United States landmass (government-owned public land), while the later is an activist movement.
  • BMS can refer to either the Be-Music Source file format used widely for chart files for beatmania and beatmania IIDX simulators, or Battle Music Stages in Theatrhythm Final Fantasy. Yeah that's right, it stands for two different things within the same genre.
  • CBT: If you get a suggestion that somebody can help you improve your life through CBT, you should probably make sure they mean Cognitive Behavioral Therapy rather than Cock and Ball Torture. Detractors have also jokingly proposed this as the new nickname for the Cleveland Baseball Team.
    • In general thanks to the infamy of the Cock And Ball Torture meme, anything that has the CBT initials tend to be confused for the torture that involves a lot of Groint Attack.
  • Which C.I.A. do you want; the Central Intelligence Agency or the Culinary Institute of America? Or "CTR Importable Archive", a common format for sideloading Nintendo 3DS software, known by its file extension .CIA?
  • "CP" is commonly used on the internet to refer to child pornography, which this poor Redditor found out the hard way when they used it to refer to Club Penguin. This also caused problems for people who made YouTube videos about Pokémon GO, as CP stands for "Combat Power" in that game, which confused the website's algorithms into thinking some Pokémon videos were inappropriate.
    Cracked caption: "Sorry for the mistaken subpoenas, fans of Coldplay."
    • In China, however, it's short for "couple" (as in shippings). It's also used in Half-Life 2 to refer to Civil Protection, the human police of the alien Combine regime, and in Minion Quest: The Search for Bowser to refer to Captain's Points, which captains use for their special abilities. There's also "Cost Points" in Mighty Gunvolt and "Competence Points" in OFF.
  • CSA: Confederate States of America or Community-Supported Agriculture?
  • DDR: Dance Dance Revolution, Deutsche Demokratische Republik, or "double data rate."
  • DMC can stand for either Devil May Cry or Detroit Metal City. Or DeLorean Motor Company — it's on the front of their cars.
  • Dead On Arrival is a standard police or medical initialism. Date Of Accident is a common insurance initialism. Given that, on any given automotive or health insurance claim, the first is a possibility, confusion has arisen on more than one occasion.
  • In the US, the early Dragon Quest games were called Dragon Warrior, leading to the DW# abbreviation. Around the time the switch back to Dragon Quest was made the Digimon World series was also starting up with the DW abbreviation. Fans of both instead insisted Digimon World was DMW, in order to avoid confusion. Additionally, neither should be confused with Arthur's little sister.
    • Not even the acronym for the newer Dragon Quest games (DQ) is safe, as it's also the acronym used by ice cream restaurant Dairy Queen.
  • ED can stand for Eating Disorder (anorexia/bulemia) or Erectile Dysfunction (impotence). Which makes certain ED drug commercials confusing, disturbing, or hilarious.
  • FF: Final Fantasy, Final Fight or Fatal Fury? Or maybe Fatal Frame? Or Fantastic Four?
  • "GM" within the context of tabletop RPGs and MMOs means "game master"; for the former, it refers to the one in charge of the game, and in the latter, they perform administrative and moderative tasks such as dealing with problematic players. Amongst Tetris TGM players, it refers to "Grand Master", the highest possible rank in every arcade TGM game. It also stands for the American automobile company General Motors, and for Genetically Modified. Also can refer to GameMaker Studio. In sports, GM stands for General Manager, which is the person in charge of player personnel decisions including drafting, trading, and free agency contracts.
  • GOW? Gears of War or God of War? Only the two series being Xbox and PlayStation exclusive respectively stops this from being extremely confusing. However, the two fandoms are actually friendly with each other about this and aside from the occasional lighthearted jest, refer to either games by the first word of the title (ie God or Gears) instead.
  • GSA can refer to the General Services Administration, the Girl Scouts of America, or the Gay-Straight Alliance, three VERY different organizations. This is made even more confusing at universities that have a Graduate Student Association. It can also mean Gender and Sexuality Alliance, a webcomic named after same, or the Galaxy Soldier Army.
  • GTA is either the Greater Toronto Area or a crime-oriented action game series. Or a DJ duo from Miami whose name means Good Times Ahead.
  • Amongst Castlevania fans, "HoD" can cause a bit of confusion as it can stand for both Harmony of Dissonance and Harmony of Despair. Fans usually use "HD" for the latter to get around this, which doubles as a reference to Despair being available on HD consoles, while Dissonance isn't.
  • You would think the acronym for Highschool of the Dead would be "HSotD". Nope, it's "HotD". Poor, poor House of the Dead fans. To add to that, the title of the games usually read "The House of the Dead" which could easily be written as THotD but it's still HotD.
  • One that used to cause a lot of headaches among Blizzard Entertainment fans - HotS: Heroes of the Storm or Heart of the Swarm?
  • IP: In the English-speaking world, especially in the U.S., it's the legal speech for Intellectual Property, while in Mexico it means Iniciativa Privada (literally as "Private Initiative", translated context-wise as "Private (non-government owned) enterprises"). However, to computer geeks, this means Internet Protocol instead.
  • IRA has at least two meanings. A big american fast-food company that set up in Britain elected to save a few thousand dollars in overheads by using its original American payroll stationery, figuring that British employees would get that they were being paid in £ rather than $ and most of the standard headings could be transposed. They ran into trouble when employees saw a heading for "IRA Deductions". In British terms, what Americans call an "Individual Retirement Account" might be "Employer/Employee's Pension Contribution". Unfortunately the acronym, in Britain, is most commonly interpreted as "Irish Republican Army" - a terrorist organisation that was very active at the time. and the story went out that employee wages were being deducted as a contribution to terrorism, and what else can you expect from Irish-Americans, they fund most of it anyway... that payroll stationery was very quickly replaced in the British operation.
  • Most Americans know IRS as the Internal Revenue Service, aka that damn bureau that residents have to pay taxes to by April of every year. Fans of Tetris: The Grand Master instead or also think of Initial Rotation System, a mechanic for making Tetris pieces spawn pre-rotated, and car enthusiasts will think of Independent Rear Suspension, a type of suspension that allows rear wheels to move up and down independently of each other.
  • JAL: In both Japan and English-speaking countries, it means Japan Air Lines. In Mexico, the same acronym is used for shortening purposes for describing the state of Jalisco.
  • KKK can mean the infamous Ku Klux Klan and the Kataas-taasan, Kagalang-galang Katipunan ng mga Anak ng Bayan,note  the most famous La Résistance group in the colonial Philippines and widely considered and revered in the nation the forerunner of the First Philippine Republic. This has caused some shock for American tourists when they see murals or paintings of the group with "KKK" proudly displayed therein.
  • Kirby has a problem with two games using the same acronym: is KSS Kirby Super Star or Kirby: Squeak Squad? The latter is sometimes referred to as "KSqSq", but not frequently.
  • In the Philippines, the acronym GMA used to have a strong confusion: When Gloria Macapagal Arroyo became the president of the country, she became very associated by her initials. The problem? There's a long-running TV channel in the country (and its aptly-named subsidiaries) with the same initials.
  • Also in the Philippines, we have the Moro Islamic Liberation Front, which, when referred to solely by its acronym in the international media, can lead to some Unfortunate Implications due to MILF more commonly meaning "Mother I'd Like to Fuck".
  • Graduating from MIT is a lot less impressive in New Zealand, where it stands for Manukau Institute of Technology, an Auckland-based polytechnic.
  • When you say you play MK, this could mean that you like playing Mortal Kombat. Or Mario Kart. Or that you like to play as Meta Knight in Kirby games and/or Super Smash Bros..
  • MHX: Mysterious Heroine X from Fate/Grand Order, or Monster Hunter X. Even more confusingly, there's also MHXX, as there's also a Mysterious Heroine XX and a Monster Hunter XX. Averted outside of Japan where those two Monster Hunter games are instead called Monster Hunter Generations and Monster Hunter Generations Ultimate.
  • MP: When referring to games, this could be Mario Party or Metroid Prime. It could also just refer to a game being multiplayer. If you're talking role-playing games, it could refer to magic points or something similar.
  • MW2: MechWarrior 2 and Modern Warfare 2. It doesn't help that both are Activision games.
  • NCR: New California Republic, or the U.S. corporation formerly known as National Cash Register? Fans of the Fallout games working for the company might find their brains a little twisted.
  • Fans of the NWA probably don't want to see the N.W.A
  • A common joke in speedrun streams is PB: personal best, or peanut butter.
  • PCB can refer to either "printed circuit board", "polychlorinated biphenyl", Perfect Cherry Blossom, or (for aerospace geeks) Plenum Chamber Burning, or the Portuguese acronym for the Brazilian Communist Party.
  • In Portuguese, PCC is usually referred for a notable crime group in Brazil or the Chinese Communist Party, which led to jokes between the two, among arguments outside jokes (no need to add further information here).
  • PDF is known primarily as the "Portable Document Format" file format, but it's also shorthand for "Probability Density Function" for statisticians. Search engines can interpret the keyword "PDF" as searching for the file type, making it harder to look up the latter term.
  • The term PMV can stand for two different kinds of Fan Vid: Picture Music Video, which is a series of still or lightly tweened images set to music, and Pony Music Video, which features imagery from My Little Pony: Friendship Is Magic set to music. Some videos are both at once.
  • PNG can refer to Portable Network Graphics, a lossless image file format, PNG Jewelers (where "PNG" stands for the late Purshottam Narayan Gadgil, a jeweler that the business derived their name from in honor), or Papua New Guinea.
  • In Portugal, PSP can stand for two things: PlayStation Portable or Public Safety Police (Polícia de Segurança Pública). Considering the police meaning of PSP has been around since the 1800s, whenever you mention PSP you usually mean the police. Additionally, PSP can also be the art program Paint Shop Pro, which in turn saves pictures as .psp by default.
  • PVA glue is polyvinyl acetate, but the initialism can also stand for polyvinyl alcohol, a different substance. Strangely, either can be used in conjunction with Borax to form slime.
  • QB: The Queen's Blade franchise, a Quarter Back, or the slightly-sinister Mentor Mascot from Puella Magi Madoka Magica?
  • In order to avoid the "RoS" confusion for the Star Wars franchise, fans have taken to abbreviating The Rise of Skywalker as "TRoS," and Revenge of the Sith as "RotS" (itself not to be confused with the "RotJ" of Return of the Jedi).
  • There are different kinds of "RPG".
  • Sonic the Hedgehog has two games that share "SA": Sonic Adventure and Sonic Advance. Adding further confusion, both received numbered sequels; SA2 is usually Sonic Adventure 2, but could also be Sonic Advance 2. Outside of Sonic contexts, SA also stands for South Australia, South America, and South Africa, among other things.
  • In the United States, "SC" refers to the state of South Carolina. Within Northern California, it means the city of Santa Cruz...unless you're in the Silicon Valley area, in which case it refers to the city of Santa Clara.
    • Gets even more fun among fans of Kingdom of Loathing, as it can stand for 'Softcore' (to differentiate from hardcore) or 'Seal Clubber', one of the classes. So you can be an SC SC from SC.
  • S.F. is either San Francisco or the initials and an alias of Konami in-house musician Sota Fujimori. Or you could be talking about Science Fiction, although God help you if you dare to use the initials around Harlan Ellison...
  • SMB could variously refer to Super Mario Bros., Super Monkey Ball, or Super Meat Boy.
  • SNK can stand for video game company SNK, or the Japanese title of the anime Attack on Titan (Shingeki no Kyojin). Some fans of the anime refer to the series by its English name to avoid confusion.
  • "SPM" can refer to either the third game in the Paper Mario series, Super Paper Mario, or the third game in the LittleBigPlanet series, Sackboy's Prehistoric Moves.
    • In Malaysia, it can also mean the final exam you take in high school (it's the local equivalent of the British GCSE O Level exams) before you move on to college.
  • SRS: Sex reassignment/reconstructive surgery, or Super Rotation System?
  • SS: Superstar Saga, Sticker Star, or Skyward Sword? Or Stardust Speedway? So Soft? A prefix used to refer to boats? Or something to do with Nazis?
    • It could also stand for stainless steel.
  • The updated release of Mario & Luigi: Superstar Saga carries the subtitle "Bowser's Minions". Referring to it by "SSBM" can potentially cause some confusion for fans of Super Smash Bros. Melee.
  • When the fifth Super Smash Bros. game was announced as Super Smash Bros. Ultimate, it was quite confusing for those who had previously abbreviated Super Smash Bros. for Wii U as SSBU.
  • "SSSS" is getting a little crowded. It may be a good idea to know what one is searching for between:
  • During the Soviet Invasion of Afghanistan, a group of German forwarding agents was captured and killed by a Mujaheddin militia after they were Mistaken for Spies. The reason? They were driving lorries with Bonn number plates, all of which read "SU" (which stands for the district of Siegburg, not 'Soviet Union').
  • SWAT, as in "Surface Water Assessment Team," came into the public eye after the 2010 BP Oil Spill. Who are likely facing wedgies of historical proportions once the real SWAT find out about their name.
    • There was a joke submitted to the Humor In Uniform section of Reader's Digest. A new graduate's parents were visiting on base and saw a van pull up that said SWAT on the side. The parents were concerned until the graduate informed them that it was the landscapers and stood for Seeds, Weeds, And Trash.
  • The Temiskaming & Northern Ontario Railway was renamed the Ontario Northland Railway due to its reporting name being confused with the Texas & New Orleans Railroad, a Southern Pacific subsidiary.
  • TPP: Twitch Plays Pokémon, The Phantom Pain, or the Trans-Pacific Partnership? Searching for "TPP Bill" will get you results for the American approval of the Trans-Pacific Partnership, although you may be looking for Bill as the villain of Twitch Plays Pokémon.
  • "TT" could refer to Telltale Games or Traveller's Tales, although Telltale is more often abbreviated as "TTG". It could also potentially be the character from Diddy Kong Racing that's named "T.T.", or the character from the also Rare-developed Banjo-Kazooie: Nuts & Bolts named "Trophy Thomas", of which both are associated with something else starting with the same initials, Time Trials. Finally, there's the Teen Titans to add on.
  • Acronym confusion appears to have been deliberately invoked by the University of Central Lancashire (UCLAn) The former Preston Polytechnic sailed close to the wind of legal action by seeking to style itself UCLA - University of Central LAncashire. While the chances of Preston being confused with Los Angeles are vanishingly small - save by those who seriously failed Geography - legal advice suggested that a small case n" should be added. The "n", in the form "UCLAn", is very small and inobtrusive.
    • They can't just call themselves UCL, because that's University College London.
  • The Brazilian Universidade Federal do Ceará (Federal University of Ceará) is officially abbreviated as UFC. The university once considered changing the acronym because of the other UFC. It helps that the official acronym for the state of Ceará is "CE", which would mean that the place should have been called "UFCE".
  • BBC News once used the logo of Halo's United Nations Space Command instead of that of the United Nations Security Council, probably because searching for images of "UNSC" online only returns results for the former.
  • American universities tend to get this in spades. The University of Southern California is rarely referred to by anything other than "USC", but alumni of the University of South Carolina always insist that they're "the real USC". Likewise, Oregon State, Ohio State, and Oklahoma State all use the "OSU" initialism, "UNH" is both the University of New Hampshire and the University of New Haven (Connecticut), and "MSU", um...yeah. That could be Michigan Statenote  or Mississippi State...or Montana State, Morehead State, Morgan State, Missouri Statenote , Murray State, or McNeese State...or Minnesota State, Mountain State, Montclair State, Metropolitan State, or Minot State. And that's just in the United States; there's also the Russian universities Maritime State and Moscow State, as well as the Indian Maharaja Sayajirao and Manonmaniam Sundaranar. Or Moldova State University, the Mahendra Sanskrit University in Nepal, the Mindanao State University in the Philippines, the Imam Muhammad ibn Saud Islamic University in Saudi Arabia, the Mahasarakham University in Thailand, the Mimar Sinan University of Fine Arts in Turkey, and Zimbabwe's Midlands State University.
  • Referring to Universal Studios Florida as "USF" around Floridians will often result in a lot of confusion, as the University of South Florida in Tampa also uses "USF" as an abbreviation.
  • In Australia, "WA" refers to the state of Western Australia. In the USA, it refers to the state of Washington.
  • The World Wildlife Fund/WWF was worried people would confuse them with the World Wrestling Federation/WWF. After losing a lawsuit over the acronym, the wrestling promotion changed to WWE and had to go through their video catalog and "erase" all WWF logos.
  • Probably, made on purpose with the Nobre e Autêntico Suporte Anatômico's viscoelastic foam pillow. Although originally designed for NASA, it was never really used by it, but the company appropriated it for its advertising.


How well does it match the trope?
