Perhaps the original is too hard to pronounce, maybe the subject in question simply doesn't have one at all, refuses to tell, [[IdentityAmnesia or just forgot it]]. For whatever reason the masses decided on a fitting name for the subject and are sticking to it regardless of any protests. They've been named by democracy. Compare VerbalTicName, where the subject will really have a hard time protesting this, and AppropriatedAppellation, where someone will adopt their title from someone else's guess or mistake. The naming of the subject has to be depicted or described to be this trope, if we don't know how it came to be it is more likely KnownOnlyByTheirNickname or EveryoneCallsHimBarkeep.

* Scar from ''Manga/FullmetalAlchemist''; his real Ishvalan name was never told and they went with Scar since it was one of the few particular characteristics they could obtain from witnesses at first. He seems to have adopted it to a some degree since he has done many things that go against the Ishval Teachings (mainly murder).
-->'''Scar:''' Long ago this body did have a holy name given by god, but that person died years ago from a life of sin, malice and retribution.
* In ''Manga/AzumangaDaioh'', Ayumu Kasuga is quickly nicknamed Osaka (after the city she just transferred from) in spite of her protests. By Year Two, this name catches on to the extent that even the teacher forgets her real name. [[{{Cloudcuckoolander}} At one point she even forgets what her real name is.]]
* This is basically how 'wolves' are given their ''nom de geurres'' in ''Anime/BenTo''; usually as a result of [[EmbarrassingNickname embarrassing situations that the 'wolf' in question is caught in]]. For instance, Satou ended up becoming known as 'The Freak[=/=]Pervert' after [[DraggedIntoDrag being seen in public wearing women's clothing]] (against his will, yes, but not that that would help him). It later turns out that Shaga got her name 'Beauty by the Lake' after [[spoiler:she fell asleep in the park after netting her first half-price meal]], and Yarizui became known as the 'Ice Witch' when [[spoiler:she unwittingly attempted to purchase a vodka mixer to go with her meal, under the impression at the time that it was a soft drink]].
* In ''Manga/SoulEaterNot'', it's revealed that students at DWMA can [[OnlyKnownByTheirNickname have their nickname treated as their official name]]--even if they don't want to, as happened with "Eternal Feather". And they won't even be allowed to change it for a full semester...

* Creator/DCComics' Solomon Grundy was named after the nursery rhyme when he told someone he didn't have a name, and had emerged fully grown from the swamp on a Monday.
* TheIncredibleHulk was an example of this trope but it's since been retconned away.
* The people start calling the thing that claimed to be from the beyond as the "Beyonder" in ''ComicBook/SecretWars''.
* ''{{Superman}}'' villain [[GenericDoomsdayVillain Doomsday]] technically doesn't even have a name (the closest thing would be "The Ultimate Lifeform" given to him by his creator). The name came from ComicBook/BoosterGold describing the creature's rampage in his [[ComicBook/TheDeathOfSuperman first appearance]] as being "like the arrival of Doomsday", which then spread through the media and became the creature's name amongst the Justice League.
* ''WonderWoman'' foe [[EveryoneCallsHimBarkeep Genocide]] does not appreciate the name democracy chose for her. She offered no alternative though so people kept calling her Genocide.
* Numerous people kept calling ComicBook/AnyaCorazon as "Spider-Girl" no matter how many times she corrected them. The codename she chose for herself in the web corps was "Araña" and even after she got kicked out it is still the title she prefers but Anya eventually relented and stopped correcting people when she realized it wasn't working.
** It's her own fault really. The name mixup started when she adopted [[ComicBook/SpiderWoman Julia Carpenter's]] old costume. People thought she a new young Spider-Woman, hence Spider-Girl.
* Minor Creator/MarvelComics villainess Crazy Eight left a CallingCard with the mathematical notation for infinity, thereby calling herself Infinity, but an ignorant cop called it "some kind of crazy 8" and the name stuck.

* ''Who Am I'': The protagonist is asked who he is in a language he can't understand. As he is amnesiac he demands to know, "Who am I?". The locals just think he's hammy and shout "Who Am I" with equal enthusiasm when they want his attention.
* In ''Film/{{Pirates Of The Caribbean On Stranger Tides}}'': The mermaid captured by Blackbeard's crew for the {{Fountain of Youth}} was named "Syrena" by Phillip in an attempt to prove a point to Blackbeard, since Phillip doesn't know Syrena's real name as it was never revealed.
* In ''Film/{{Tremors}}'', the townspeople have a spirited discussion about what to call the underground monsters menacing them all, finally deciding on "graboids". The person who came up with the name is killed soon after.
* ''Film/SawII''. John Kramer introduces himself to Eric Matthews using his real name. When Matthews says he thought John preferred to go by "Jigsaw", he says that's just the name the media stuck him with.
* ''Film/WarForThePlanetOfTheApes'': Maurice refers to the little girl they had found as "Nova", even though it's not her actual name. This is due to the fact that she is suffering from the Simian Flue that makes her {{The Speechless}} and thus cannot tell them her actual name.

* The Black Tower of ''Literature/TheWheelOfTime'' is an example of a place whose name was agreed upon by its residents, to differentiate from the white tower their counterparts work at.
* The Inscrutable Machine in ''Literature/PleaseDontTellMyParentsImASupervillain'' is the name Penny came up with for herself, but she eventually ended up with Bad Penny, with the trio as a whole as The Inscrutable Machine. Generic Girl didn't pick the name for herself either, as she's all business and doesn't take the time to chat.
* This, along with BreadEggsBreadedEggs, gave secret heir to the throne Tomjon his name in ''Discworld/WyrdSisters''. When Mrs. Vitoller, his to-be adopted mother, asks Granny Weatherwax and Nanny Ogg what his name is, they don't know what the king actually wanted to name him, so they simultaneously say "Tom" and "John," then settle on "Tomjon."
* The main character of ''Literature/{{Worm}}'', Skitter, gets named by the Wards. She doesn't particularly care for it, [[spoiler:and later changes it to Weaver.]]

[[folder:Live Action TV]]
* ''Series/BabylonFive'': Some aliens have a name that is a thousand letters long and cannot be pronounced by Humans. Then their adherents whine because everyone keeps calling them "The Shadows".
* In ''Series/SpartacusBloodAndSand'', after seeing the title character's performance in the arena, the Romans name him "Spartacus" after a legendary Thracian king. He is at first insulted, and [[TheUnreveal tries to introduce himself, but is interrupted each time]]. He eventually accepts the name.
* Fez from ''Series/That70sShow''. His real name, which was never revealed to the audience, is said to be really long and hard to pronounce. Fez is short for '''F'''oreign '''E'''xchange '''S'''tudent.
** Interestingly enough, the show's original working title was different; the members of the test audience (focus groups) kept calling it "that 70's show", and the title was changed.
* In ''Series/{{Haven}}'', a SerialKiller who murders people by shooting them in the back of the head with a bolt gun is nicknamed the "Bolt Gun Killer" by the police. In a fight against Duke Crocker, the killer says that nickname is stupid.

[[folder:Mythology, Religion and Folklore]]
* ''Literature/TheBible'': Obed, son of Ruth and Boaz, was not named by them but by their neighbors.

[[folder:Professional Wrestling]]
* [[Wrestling/GeorgeSteele George "The Animal" Steele]] was originally George "The Bruiser" Steele but the fans kept calling him "the animal" until it became official.
* While Tomomi Tsuruta was competing in Amarillo early in his career, a fan contest led to him being renamed "Wrestling/{{Jumbo|Tsuruta}}".
* Wrestling/JerryLynn debuted in Wrestling/{{ECW}} in September 1997 as "Dynamic" Jerry Lynn. During his feud with Wrestling/RobVanDam, who uses as one of his {{Red Baron}}s "The Whole F'n Show," the fans started calling Lynn "The New F'n Show."
* Wrestling/FergalDevitt ended up being known as "Prince" Devitt in Japan because hardly anyone could remember how to pronounce "[[JapaneseRanguage Fergal]]".
* After Wrestling/EvanBourne and Wrestling/KofiKingston became tag team champions, a poll was held on Twitter to decide on what the new tag team would be called. Air Boom has been derided by some, but democracy had spoken. Earlier in Wrestling/RingOfHonor, Matt Sydal(Bourne) had teamed up with Fast Eddie and were named, "Air Devils" by the fans, so this was not a huge surprise.
* On their website, WWE asked their fans to vote for names of the various shows their network would air.
* Cheeseburger got his name after Rhett Titus and [[Wrestling/TheWorldsGreatestTagTeam Charlie Haas]] saw him in [[StrangeMindsThinkAlike two separate instances]] and decided that's what he needed. The latter calling him such during a match lead to the fans cheering it and ROH creating a "Cheeseburger" t-shirt, which became a best seller in ''Wrestling/{{New Japan|ProWrestling}}''. So Cheeseburger came to embrace the name he initially hated.
* The team of Wrestling/{{Kane}} and [[Wrestling/BryanDanielson Daniel Bryan]] was bestowed the name Wrestling/TeamHellNo by a poll on ''Raw''.
* Successfully {{defied|trope}} by La Sombra and Rush in Wrestling/{{CMLL}}, whose trio with La Mascara was originally dubbed "Los Indeseables" based on the fact no one wanted anything to do with them but officially became "Los Ingobernables" thanks to their insistence.
* "The Punishment Damian Martinez" was almost exclusively billed as "Punisher Martinez" until the full, correct ring name was [[DefiedTrope forced into recognition]] by Ring Of Honor once they decided to use him regularly.

[[folder:Video Games]]
* One ''VideoGame/{{Tekken}}'' character told the orphans his tag team partner looked after that he didn't have a name they could hope to pronounce. Their response? "You do now!" It was Armor King.
* Chaos Lord from ''VideoGame/DigimonWorld'' is named by the other Digimon, which is notable because Digimon usually don't give [[PlanetOfSteves individual names to anyone]].
* Garrus of ''Franchise/MassEffect'', when anonymously [[WeHelpTheHelpless doing good works around Omega]], is called Archangel. When Shepard finds him, he asks you to just call him Garrus.

[[folder:Web Comics]]
* In ''Webcomic/ElGoonishShive'', Elliot's [[SuperGenderBender superheroine]] name was chosen by the (InUniverse) Internet latching on to [[http://www.egscomics.com/?date=2010-11-10 Justin's comment]] about Elliot's superheroine form's skirt looking like a cheerleader's. As a result, Elliot gets "Cheerleadra" as his superheroine name.

[[folder:Web Original]]
* In ''Machinima/RedVsBlue'', Church decides that their new medic's name [=DuFresne=] is too hard to say, and dubs him "Doc" instead. Doc protests that [[InsistentTerminology he's not a doctor but a medic]], but everyone else overrules him and goes with Church's idea. He never bothers protesting again after that, and everyone just continues calling him Doc (though he does always refer to ''himself'' as [=DuFresne=] whenever the matter comes up).
* {{WebVideo/Phelous}}' unnamed video show was called "Phelous And The Movies" on IMDB. After joking about it for a bit, he eventually decided to adopt the name.

[[folder:Western Animation]]
* ''WesternAnimation/SamuraiJack'': The time displaced hero was called "Jack" by the first friendly people he met in the future, who were using the term "jack" in the same vein as "dude" or "bro." Jack, however, ends up adopting it as his name, never revealing his given name at any point in the show.
* The titular character of ''WesternAnimation/DannyPhantom'' gets rather annoyed that after TheMasquerade is blown everyone around town knows him as "Inviso-Bill" until he sets the record straight in the first MadeForTVMovie.

[[folder:Real Life]]
* Dave Sim (creator of ''ComicBook/CerebusTheAardvark'') once mentioned how several grown-up members of his family spent several hours naming the new cat, finally settling on "Puss". He took this as a sign that DemocracyIsBad.
* [[TheCaligula Emperor Gaius Julius Caesar Augustus Germanicus]], known by the nickname given to him as a child dancing for the armies in Germany in a little soldier's outfit, "Little Boots", ie, Caligula. According to Seneca the Younger, Gaius hated the nickname "Caligula", and punished anyone who used it during his reign...yet he couldn't stop the masses.
** It didn't really help that his three predecessors as emperrors were called ''Gaius Julius Caesar'' (''the'' Caesar), ''Gaius Julius Caesar Octavianus'' (Augustus), and ''Tiberius Julius Caesar Augustus'' (Tiberius). Also, [[PlanetOfSteves the two men who followed him as Emperor were]] ''Tiberius Claudius Caesar Augustus Germanicus'' (Claudius) and ''Nero Claudius Caesar Augustus Germanicus'' (Nero), making the name stick to him for eternity.
* In contrast to how military pilots in fiction are pretty much guaranteed to have AwesomeMcCoolname call signs, in real life they're often joking or even insulting because the nicknames are dreamed up by the pilot's fellow students or even the instructors in flight school, hopefully due to a MomentOfAwesome but more likely something they consider an OldShame (but which their peers found to be a CrowningMomentOfFunny). Go into fighter school expecting a name like "Maverick" and you might come out, after an unfortunate incident involving a negative-G maneuver and some bad breakfast, having "Upchuck" stenciled on your cockpit.
* In 2016, an Internet poll was held to decide the name of a new research vessel. The Internet, being the Internet, quickly pushed "Boaty [=McBoatface=]" as the leading choice. [[https://en.wikipedia.org/wiki/RRS_Sir_David_Attenborough While the ship was named]] after Creator/DavidAttenborough, [[https://en.wikipedia.org/wiki/Boaty_McBoatface Boaty McBoatface]] was used for one of its unmanned subs.
