Bro, the other night at the party everyonethought Ashely was cool, but she turned into a total queef.
A wet flappy fart noise that is emmitted from the pus when air is brought into it. It usually creates a sloppy "ppppfffftttt" noise followed by a wet fart and the rapid flapping of pussy lips. Sometimes white chunks of seman have been known to fly out of my friendsvagina.
