The release of anal gas, the culprit having his/her pants (and underwear) far enough down so that the methane gas avoids contact with his/her attire. This method will prevent underwear "stink", and the lack of a barrier between anus and ambience will cause the fragrance to spread quicker and with richer concentration.
A BBF (noun) also known as a Bare-Bum-Fart is a farting position where one lowers their trousers and underwear, then parts their bum cheeks and breaks winds allowing the gas to seep into the surrounding area free from filtration of the layers of clothing that may cover the bumhole region.

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.
