A bum pirate is one (usually a male) who frequents night clubs and other social hotspots and then, after drugging their victim with rohipnol, proceed to sodomise them; hence, they are "pirating" people's "bums".
It may also refer to anyone preferring to anally rape their victims.
Jeffrey dahmer was a bum pirate of note.
Bum pirates usually go to jail if caught, where they in turn have their bums pirated.
