1. The Southern equivalent to the North's "Lock Jaw"
2. (Noun)A condition that occurs when a person has been sucking too much dick, and begins to feel an ache in their jaws. Can sometimes result in "warp" to the jaw, where a person keeps their jaw in a weird position as it tends to relieve the aforementioned ache.
Ex) As I was watching the guy walk down the street I noticed one side of his mouth was slightly contorted, and thought he might be the victim of a stroke. However, upon closer examination I saw his "Girls Kick Ass" T-Shirt and very short cut-off denim shorts, and realized this man was suffering from Warpy Jaw.
Ex 2) Man 1: Dude I really don't want to go see the movie

Man 2: Dude you are such a little warpy jaw bitch!!!
