look up any word, like half chub:
 
1.
Misspelling of the word 'pederast' made popular by The Big Lebowski. Webster's defines it as "one who practices anal intercourse especially with a boy."
Walter: When he moved down to Venice he had to go door-to-door to tell everyone he's a pederast (not petterass).

Donny: What's a pederast, Walter?

Walter: Shut the fuck up, Donny.

A "petterass" has nothing to do with pedophilia, peters or asses you guys. Petterass is a way of calling someone PETTY and refers to something/body which is a trifle, unimportant, petty, minor matter or small. You would be more accurate to say someones small peter is petterass, but it really refers to their actions and attitude. Again-- petterass as meaning petty, small and minor doesn't refer to some guy petting small minors. HAHAHAHA!!! That is rich!
His critique of our definitions was petterass and banal.
