Used by skateboarders (who get videotaped by their friends doing jumps off of staircases and face-plants into the concrete floor below) as a replacement for chewing gum. The more fillings you have in your teeth, the better it tastes.
Dude! I can chew aluminum foil and skateboard at the same time! *face-plant splat!*
