ass shrapnal 

Noun - This substance is emitted with an abundance of force, excreted from the anus. It is so explosive and nasty that irregular foot taping or whistle'n should be performed in unison with the act to cover your tracks and distract any bystanders.

BASF (Bare Ass Shrapnel Fart) 

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.

ass shrapnel

The little bits of feces, toilet paper, string, and other flak that collect in a man's ass crack.

His fart wasn't enough to clear out all of the ass shrapnel that had collected during the week.
