tennising
When two guys are simultaneously sex with a girl and she bounces inside of one to the other, much like a tennis ball going back and forth.
Person 1: Hey, Brad and I were tennising this girl last night so hard, she bounced off the bed!
Person 2: Brad, you are such a douchebag.
Person 2: Brad, you are such a douchebag.
