Alabama Underbite 

When an inbred looking girl without teeth is going down on you and then sucks your balls from below, not under, like a fish to bait.

Undertesticle 

The underside of one's testicular package. Worthy of note when describing precisely where you were hit by a hockey puck as the degree of pain is significantly greater when struck on the underside of a jock as opposed to straight on.

Neil blocked a shot in the undertesticle, and later blacked out on the bench.
