Rash

That guy that follows you around, thinks he's friends with you, and doesn't understand when you tell them you want them to leave. Comes from the traditional form of rash, which is irritating and also difficult to remove.

Guy 1: Hey, wanna catch up this weekend?
Guy 2: Sure.
Rash : Cool, when are we meeting?
Guys 1 & 2 : Fucking rash.
