When an individual is lazy or tired and takes a bite out of food. The person takes his or her piece of food (Pizza, for example), holds it above their head, tilts their neck back, flips the food the other way (So the back of their hand is facing their head), and loosely puts it downward into their mouth. This is usually accompanied by a moan of delight.

Found predominately in rednecks – when the lower teeth grow or extend past the upper teeth. This condition, if not fixed at a young age can cause digestion problems and also increase the risk of biting one’s own tongue.
