cock knocker

A really dumb guy. The kind of exceptionally dumb guy who whacks his hardon against door frames and shit, literally knocking his cock.

Especially applicable to a guy who sucks, yet has a rad girlfriend.

"Ditch that guy, like yesterday. Your boyfriend is a fucking cock knocker. You could do so much better. Like me."
