Party Ma-Sheen 

A hard core partier. Not just a party machine, but a ma-sheen: someone on the same level as Charlie Sheen. Someone with a tiger alcohol blood content who thinks they're a winner ... but is actually a loser.

He sniffed coke off a stripper's tit! I can't hang with him, he's a party ma-sheen.
