last in line for the gang bang

Originating from the title of a song by Boston psychopath/frontman GG Allin that was, in fact, actually about being last in line for a gang bang. The term is somewhat uncommon, but occasionally used by people in the New England hardcore and punk scenes, where it refers to someone who is late to a trend (or late to drop it), unaware of big news or changes, or generally clueless. It can be used against oneself or a friend in a comically self-depricating fashion, or against someone as an insult.
