The act of cawing and flapping your arms like a raven while penetrating a female (or male) in the ass. It is key to caw louder the deeper you go to achieve maximum raven flapping. After you have blown your raven load you position the female (or male) on all fours and “peck” your semen out of their ass, letting out a loud raven-like coo after swallowing.
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 flappinglast night"
Kelly: "Oh i got sack flapped last wednesday; and his beanbag bruised the hell out of my tummy "
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 clubtonight.
