The sound one makes when masturbateing to porn on a laptop computer. Also can be the sound mad when your pounding a honey hole and your ballsack and ramrod slam against those meaty lips.
We got home early only to walk in our apartment and hear the sound flap flap flap flap flap flaaaaaaap flap of Tim our virgin roomate wackin off to porn on his laptop.
