BBF (Bare Bum Fart)

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.
1. Anna BBFed before her first date with Tom so that her underwear didn’t have brown stains on.

2. ‘Oops’ said Tom as he lowered his pants, ‘I must of forgotten to BBF (Bare Bum Fart) at some point today. My pants are brown, Mummy isn’t going to be happy.’
