Sack Flapping

The sound your ballsack makes when pounding a tight slizz from behind; a good sack flap goes to a beat and makes a soft thumping noise... & can lead to minor bruising and irritation of the stomach region of the partner whos tight slizz or smelly balloon knot is being ravaged

Kelly: "Whats that on your stomach?"
Sara: "I had a good Sack flapping last night"
Kelly: "Oh i got sack flapped last wednesday; and his beanbag bruised the hell out of my tummy "

flapping

shaking one's willy in an eccentric and exciting manner. often resulting in hilarious and wet consequences. can be used as a form of foreplay or to attract other people to engage in the mating process, much like a peacock displays her feathers to attract a mate. a male human will often display his willy in an appealing way to gain sexual prowess.

i am going to use my extreme flapping capabilities to attract a mate at the club tonight.
