All men who fuck up by insulting their girlfriends. Insulting or mocking your girlfriend in a casual yet highly offensive way. This is often intentional and done for amusement, but can also be due to carelessness. Either cause leads to great entertainment and raucous laughter among friends while the woman explodes in anger and the "lacey" contemplates the prospect of a night without sex. Must hold substantial comic value for onlookers.
