What is Clapping H?
A sex act involving two guys and one girl. While the girl is on all fours, one man gets the chick from the rear section, the other "face fucks" her. While thrusting, the two men clap their hands over top of the girl. Their bodies form the letter 'H', thus creating the Clapping H.
Dude that total slut let me and my dude complete the Clapping H
