raven flapping 

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.

Rob was raven flapping the shit out of her last night after that big wedding. Thomas looked on in admiration and slight jealousy.
