Occurs when a man rips an especially violent fart at the moment of orgasm thus adding a jet thrust to further explode his seed into the womb. Some men derive extra pleasure from the act of expelling their flatulence whilst they orgasm. Not for the feign of heart, it should only be utilized at the end of a relationship, with a fat chick, or with a really good humored mate.
She didn't like the jetgasm, but man it felt good as hell!
