Sons of bitches that sit behind you in a movie theatre and either; Chew their popcorn with their mouth open and don't realize that everyone around them is getting annoyed. Or, those bastards that breathe extremely loud and decide to let everyone know.
Annoyed person 1: What the hell is that noise, i'm trying to watch this movie!
Annoyed person 2: It's those damn sphincter spix behind us!
