Slapped your dick against the wall

when you hook up with a girl that should not be present in broad daylight. The term comes from the fact that you'd have been better off slapping your dick against a wall for some form of pleasure than putting it anywhere near that creature's hatchet wound.

Dude I can't believe you banged that skank last night...should've just slapped your dick against the wall..
