A “Qwauff” is air leaving the anus after two men have had anal sex or after a man has been pegged.
A qwauff can and is often times mistaken for a fart. Anyone who may hear a person qwauffing, may believe they are simply farting as they sound exactly the same.
A Qwauff is the equivalent of the female form “Queef” (air being expelled from the vagina, usually after sex).
Person 1: “WAKE UP AND TELL ME WHO YOU’VE BEEN HAVING ANAL SEX WITH!”
Person 2: “Why are you accusing me of having anal sex??”
Person 1: “I’M NOT AN IDIOT, I’ve been hearing you Qwauff all night!”
