The process of farting out of your dickhole. Like Queefing, but with your dickhole. A deef does not smell like fish, like a queef, but like fresh spring flowers spewn accross a medow with bunnys. A deef tends to sound like a gunshot, and priests and african americans are alergic to them.
Yesterday i let out the craziest deef in church, the priest threw up on the alter, i think he was a black.
