The opposite condition of a Jared. The appearance a man/women/child gets when they partake of more than the recommended quantity of McDonald's happy meals or Big Macs. These person's ultimately grow into the outward appearance of Grimace, other than the purple color. The first warning sign in the transformation is the growth of a FUPA and quite possibly a moose knuckle. Unfortunatly many of these Grimace Gut owners do not know of their swollen condition and unintentionaly flaunt their goods in the site of the public eye. Somehow they are still able to wear thongs and 2-piece bikini's, much to the distress of onlookers.
