In TV Land, most characters will freak over gaining a few pounds, and instantly pull out the carrots and celery. And those who are overweight will usually try to deny it. But not these guys (or at least not anymore). These are the few, the proud, the fat. They have no qualms about their size and will complain when they lose weight. They may even try to gain more weight, although this is not seen as often. If female, this character is almost always a Big Beautiful Woman; Big Beautiful Man if male. Sometimes they are Big Eaters. They might also be strong, quick, and resilient.
