when a couple has anal sex, the male waits for his wife to fart and simultaneously fucks her in the ass, thus punching the fart.
my new girlfriend lets me fart-punch her all the time.

When someone drops a fart of such magnitude that you react as if you were physically punched in the face. Its like being assaulted by death.
I was in the elevator at work and i swear to god Jack delivered a Fart Punch to every one of us in there. I didnt here it coming but when it hit i cried like a little girl that just learned life has consequences.
