A type of leather pants (usually worn by bikers) that are
little hit and
miss. Or rather, miss and hit. They'
re missing the ass, which allows that ass to be hit.
Dude: What's the deal with your pants? They seem to be missing the ass, for hitting the ass.
John: Oh, yeah, I
love wearing assless chaps! C'mon smack that ass.
Mooch Mooch.
Dude: Um, yeah starts running as fast as he can in the other direction.
