To have an orgasm while flatulating. Usually preformed by a woman, because it doesn't happen to them too often. (The act of flatulance)

Frankie has to fart real bad, but decides to hold it in fear of turning his girlfriend off during sex. The result is- WHAM- an instant orgasm caused by the stress of holding the fart in. And hey, the fart stays in. There, a fartgasm.
