In English-speaking circles, [[GratuitousJapanese going out of one's way to use the Japanese words for things that are typical of anime in general when the English equivalent would suffice]] is considered to reflect poorly on the speaker; for instance, saying you dig ''vampire catgirls'' isn't a big deal, but going to the trouble of saying ''kyuuketsuki nekomimikko'' will put you on the Chumptrain to Douchetown.

** And classical music fans who like the idea of continuing to breathe without medical help would be advised to ''not'' claim a fan of film/Broadway music doesn't like "real" music.

* In the world of LewisCarroll's ''Hunting of the Snark'', if your snark[[labelnote:*]]no, not ''[[DeadpanSnarker that]]'' kind[[/labelnote]] happens to be a boojum, "you will softly and ''suddenly'' vanish away, and never be met with again." ''Not'' "softly and ''silently''". This did cause arguments [[OlderThanRadio way back then]], with one fan, [[OnlinePersonas Snarkophilius Snobbs]], becoming infamous for persisting with this misquote.

* In the presence of hardcore [[LewisCarroll Carrollians]], never refer to the Hatter as the Mad Hatter, or to the Jabberwock as the [[IAmNotShazam Jabberwocky]].

* Using the suffix -ception to imply a thing inside a thing inside a thing is certain to get you a scolding if you go into the bad parts of the ''Inception'' fandom.

** When Pokemon was first starting to get popular, kids would cringe whenever their parents (or some other adult figure) pronounced Pokemon as "Pokey-man" or "Pokemons".

* ''HarryPotter'' fandom is large and diverse enough that almost anything is acceptable in some circles, but in general the following rules hold:
** '''Technology at Hogwarts''' isn't permissible in any dose.
*** Things that work electronically, as below, ''do not work.'' Things that work ''mechanically,'' such as Harry's watch, do work.

*** ''MyImmortal'' deserves mention just for the sheer fact that it manages to break pretty much every FandomBerserkButton rule in a spectacular CrossesTheLineTwice fashion.

* Jim intentionally did this to irritate Dwight on ''TheOffice''. After an ethics meeting where they were told to avoid "Time Theft" in the workplace, Jim had a deliberately loud conversation with Andy about the ''Series/{{Battlestar Galactica|Reimagined}}'' TV show. During that conversation, he talked about how the show has [[Franchise/StarTrek Klingons]] and [[StarWars Wookiees]], is a shot-for-shot remake of the original, and is about a character named [[HarryPotter Dumbledore]] [[StarWars Calrissian]] who has to [[TheLordOfTheRings return a ring to Mordor]]. Meanwhile, Dwight is seething at his desk, trying his hardest to refrain from getting involved in this non-work-related conversation.

* Don't even think about calling ''WorldOfWarcraft'''s ''Mists of Pandaria'' expansion a ripoff of ''KungFuPanda''. Pandaren were first introduced in ''Warcraft 3'', five years before the movie was released.

* Pick a stadium in the US that's recently been renamed by a corporate sponsorship. Any stadium. Try calling it by its sponsor name in a local sports bar. For example, "I really like going games at 3Com Park," or "...Monster Park.' Proceed to get beat up by the guys who insist that it's "Candlestick Park" and it will [[PunctuatedForEmphasis ALWAYS BE CANDLESTICK PARK!]]. Go to another city and repeat.

** The Ultramarines themselves are polarizing. Even before Ward changed the fluff to make them the "default" loyalist army they were scorned by non-Ultramarine players because they were GW's poster boy army. However Ward's comments that every Space Marine chapter secretly looked up to the Ultramarines and beheld their primarch Roboute Guilliman as their "spiritual liege" whom they all aspired to emulate really set the Ultramarines hate to a new level. Bringing up the Ultramarines won't get you into trouble in and of itself, but mentioning the title "spiritual liege" will. Especially from a Space Wolves, Black Templars, or Blood Angels player.

** Space Marines armies aren't "pretty much all the same". There are myriad differences between the named codices, much less the various ways the plan Space Marines codex is interpreted by players.

** It also is NOT a "tablet", it's a tablet controller.

* Go ahead, use BC (Before Christ) and AD (Annos Domini) when talking about dates, rather than BCE (Before Common Era) and CE (Common Era) around history buffs. [[BlatantLies You totally won't have your head bitten off]].

** Do ''not'' ask for a FanTranslation of ''Mother 3'' that has no profanity in it. Aside from being just plain ungrateful considering how long said fan translation was in production, the first such member to raise a fuss over the issue was ''extremely'' immature about the whole thing (although the member in question has long since gotten over it).

* The surprisingly widespread popularity of ''VideoGame/{{Slender}}'' led to a sudden wave of newcomers to the fandom who [[IAmNotShazam think the title is the name of the main antagonist]]. This is almost guaranteed to send long-term [[TheSlenderManMythos Slender]] ''[[TheSlenderManMythos Man]]'' fans into an eye-twitching rage.
** In that same vein and depending on the forum/blog you're commenting on, saying [[FanNickname Slendy's]] full name is "Slenderman" rather than "Slender Man" will get some fans of the Mythos very, ''very'' angry with you. Other fans really couldn't care less how it's spelled, as long as you're not calling it "Slender".

** Do not call an individual unit selected from ''Codex: Black Templars'' a singular "Black Templar". You can call them by their unit names when all else fails. You can also call them an Initiate or a Crusader.
