If there's one thing fans are good at, it's making up new words, or new uses of already existing words/punctuation (like the exclamation point in things like fanon!Draco, or the background of the word "slash").

Hell, the word "fan" is a shortening of the word "fanatic," but I have no idea how far back that goes.

I mean, like, seriously. Crackfic, mary-sue, britpick: fanfiction is just full of its own made-up words.

Out of curiousity, what don't you like about the idea of fanfiction?
