cock block

The friend that you have nothing in common with, but you seem to wind up hanging out anyways. Often interested in space, fantasy games and gaining weight. Forms an impenetrable barrier between you and good looking women.

Wanna hang out with Sam?

That dude is the biggest cock block. Hell no.
