BASF stands for Bare Ass Shrapnel Fart. To do a proper BASF one must drop one's drawers and sit, bare ass, on a hardwood floor and then rip a monster fart. The vibration of the buttcheeks against the hardwood creates a natural reverb chamber/amplifier resulting in a thunderous cacophony akin to a gunning a chainsaw while firing an M-16.
Joe's BASF (Bare Ass Shrapnel Fart) blew a hole through the parquet and now the Celtics have to play home games at Sacred Heart until they fix it.
