look up any word, like tribbing:
 
1.
a scooter riding son-of-a-gun who thinks he's all priviledged and shit. talkin' politics and buggin' the shit out of everyone he comes into contact with.
that first class ass just pulled out his pecker and said "hey look, george bush is running for a third term.....c'mon give him a smack."

2.
-The asshole of all assholes.

-An asshole who is more of an asshole than any other asshole you've ever met.
Greg: Hah! Remember that girl you were trying to ask out for the longest time? I fucked her last night.

Fred: Fuck you Greg! You're a first class ass, you know that!?
