Fat Flapping

The action of getting volatile and angry over a minute and niche thing of something that's praised.

Friend 1: Hey, did you hear about that new Left 4 Dead 2 update?
Friend 2: Yea, I hear it's awesome! Though I did hear one dude complain that the update ruined his mods.
Friend 1: Don't mind him, he's probably just some fat flapping weeb who's upset that his 150 Hatsune Miku mods don't work no more. Let's go play!
Friend 2: Ight, bet!
