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.

Ol' girl was going at me good and then dropped her dentures and hit me with an Alabama Underbite.

Severe underbite

Severe underbite -- when it smells like pussy but it tastes like shit.

She smells great but tastes funny -- I must have severe underbite.
