Making your hand into a "thumbs up" position, and then hitting someone in the butthole with the thumb while screeching "Beaver claw!" This is normally done through the clothing to someone bending over.

Punching/hitting/slapping someone in the nuts, and then proceeding to beaver claw them in the ass when the bend over. Make sure you yell "JOLLY!" while in the process.
Dude, I gave a jolly roger to Chris yesterday. He got hurt so bad he was holding his regions for like 15 minutes.
