The post-hookup fart occurs after a male hooks up with a girl the night before and has been holding it in all night in bed, and during intercourse. The next morning after she leaves, the male relieves himself with a powerful gassy eruption that has been building up for more than 12 hours due to embarrassment of farting in front of a random girl you are having sex with. The post-hookup fart exponentially increases its intensity in correlation to the amount of beer drank the night before.
Wallace- Dude, that was the loudest fart I have ever heard. It sounded like a tuba. You must have gotten laid last night.

Frederick- Ya man, I totally put it in her. Holy shit that feels so much better. Sometimes the best part about banging a random chick is the feeling after the post-hookup fart.
