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.
"Steve was so high last night! He had a twinkie and did the Fat Man Bite on it."
