After getting the oppurtunity to put your dong in someone else's butt, you begin. After insertion, carefully begin to pee into the butt, waiting for the time when the reciever begins to turn around. At that point, give him or her a backhand as only roger federer can give, showing your reciever who's the real roger federer, and that he or she most definetly cannot fuck with you again

Matt : Nah, man. I couldn't get her out of the fucking house. She was slamming the clam for like five hours!
Mike : Damn, man, she's gotta be chafed after that.
