The act in which one human being, who is mentally disturbed, uses the molar joints (which are capable of inducing 600 lbs of crushing force) against an unsuspecting individual to the buttocks...with intentions to permanently leave teeth marks, and possibly even cause scarring. The meeting point of impact, between such teeth and the meat of the cheek, results in a severe jump, followed by a scream to be heard from the harassed individual. Then witnessed is usually tears from the victim, as he/she (usually HE)collapses to the ground, holding the damaged cheek while in the fetal position.
I want to go ducking on your cute little right cheek... are you ready???
