A painful blow job that is the result of the giver incorporating too much teeth into their bobbing of the knob. This painful teething of the cock causes the male to clench their own teeth and often grimace in pain. However, the male receiving will generally endure the pain because even though it hurts, any sucking of the cock is good.
