A superfink is an act, performed by one friend, on another, which can include everything from not showing up to a party after promising to do so, to stealing a friend's girlfriend.
Stan: Yo man, what the hell happened to Sam? He looks like hell and I've never seen him drink that much.

Stan: Wow, Sal's a real piece of shit, and Gretchen's a whore.
