A man who decides to go on a diet and throws away all his junk food, only to eat it out of the trash later that night because he can't control himself. He is usually so ashamed of his fatass that he won't get up from his seat at the movie theatre even when he really has to pee (and poop all the food he ate; he is embarassed that his fat ass will brush across everyone's face because he is so fat.
