Squee: The noise you make when something is so good that all you can really do is squeak or squeal. A high pitched sound of delight, often accomanied by hugging yourself or others.
Squick: A fic/art/concept/topic that is repellent to you, so you reject association with it and instead retreat to your personal comfortable spaces- all the while remembering that someone elseâs comfort is not your own.
YKINMKATO: Also called âkink tomato.â Abbreviation meaning âyour kink is not my kink, and thatâs okay.â Used to explain why you are rejecting art or fic brought to you by someone else. A solid mantra to recall instead of sending flames in peopleâs comments
Flames: The comment equivalent of anon hate.
AMV: âanimated music videoâ or âanime music video.â Often, this is stylized to fit a specific fandom, such as a âPMVâ (pony music video) in my little pony. May also be referred to as a lyricstuck.
Filk: Combination of the words âfilmâ and âfolk,â this is a music genre, to which âfan songsâ and âfan parody coversâ belong. If you donât really understand what this means, take a quick listen to American Pie, then compare Weird Al Yankovicâs Saga Begins
BNF: Big name fan. You know that one person who is just so fuckign popular in your fandom? Their art is always on your dash, everyone knows their fics? Being spoken to directly by them is basically being noticed by everyone everâs senpai? Thatâs what these people are called.
DL:DR; Not unliked the teal deer (tl;dr, or âtoo long, didnât readâ), DLDR means âdonât like? Donât read!â Itâs a reminder that you are under no obligation, ever, to expose yourself to uncomfortable (or, squicky), or potentially harmful (or, triggering), material. Not ever. If you donât actively like something? Itâs not worth your time. Skip it.
Gen: or âgenficâ âgenartâ etc. Fan works which contain no or very little romantic content. Often these are styled after the canon material, and may be called âepisodicâ ro âslice of lifeâ in addition.Â
Lemon: Work containing strong pornographic elements
Lime, or Citrus: Work containing mild or implicit pornographic elements
Sockpuppeting: The surprisingly common scenario of someone making a bunch of fake accounts/sideblogs to send themselves reviews or hate, to try to increase views or drama surrounding a work. The accounts they make are called Sockpuppets.Â
WAFF: Warm and fluffy feelings. A genre of fic that exists just to be therapeutically sweet. Nowadays, usually just called âfluffy.â
Schmoop: Take WAFF and somehow make it even more syrupy. Youâll know it when you see it.
Whump: Imagine if you will, a hurt-comfort fic. The comfort might be considered WAFF. The hurt? Thatâs the whump.
Wapanese: When white autors pepper their anime fanfic with random, tonally inappropriate japanese words.Â
Anthropomorfic: Nowadays we just call these âhumanstuckâ or âhumanized AU.â
Wank: Wildly disproportionate drama that crops up because someone wrote/drew/did something that someone else didnât like. Seriously, I cannot begin to express the fiascos that have come about from all this. Just⌠Just go look at this.
 Plot bunny: Story ideas that you probably wonât ever actually deal with, but that multiply entirely out of control, creating huge worlds in your head that youâre probably not going to write. But hey! You might! And until then they make great sideblogs/askblogs/tumblr posts.
Casefic: Fanfics that try to create an episode-like feel for procedural and crime dramas, moster of the week shows, etc.
Jossed: When popular fan theories and fanon are addressed in the canon of a series, and whoops, turns out we were all very, very wrong.
Kripked: When popular fan theories and fanon are addressed in the canon of a show and, hot damn, we fucking called it.
Secret Masters: The people who run the websites/ communities/etc that we all do our fanning on. Less relevant now that we have things like tumblr, but when everyone had to run their own archival and social sites for each fandom, it was more important to pay our respects to the strange and powerful beings that brought us all together and gave us our fannish homes. Think the staff of AO3, for example.
Bashing: When a writer purposefully writes a specific character as a horrible, horrible person so that they can throw them out of the storyline, usually to allow their OTP to get together without trouble. Distinct from fridging in that it doesnât require the character to die, but rather to be such a screaming harpy that they get rightfully removed from the main charactersâ lives for being an abusive hell beast. Generally, a type of character hate. Be wary of people who bash women, queer people, and POC with consistency: they are not safe to be around.
