A variant of wet willy, combining the best aspects of Pop Rocks and wet willys. The person licks or spits on their
finger, and then dips it into the Pop Rocks bag coating the
finger tip with a layer of Pop Rocks. Then the attacker sticks this
finger into the victim's ear canal and twists. The key is to have ample saliva on the finger such that the Pop Rocks start popping right next to the ear drum!
