An emission of methane from the anus which, when ignited, can cause great hilarity. Regarded by eco-types as an (admittedly noisome) solution to the environmental crisis.
A minorturd. A fart is an explosion, some may be so powerful wen sitting down, they come out from the front but.
when sitting down i felt some powerful gas run through my body, but so powerful it came out near the vaginal area.... almost blew me away!it was one mighty fart!
