A loose, short sleeve, button down shirt, the entire fabric of which, including the sleeves, collar, and back, is silk screened with an image, generally an epic action scene such as a wolf surrounded by lightning or a character or action scene from a comic book or cartoon. Often times, however, it features flames, spider webs, or something else lame. Termed "buffet shirt" because it is generally worn by fat people, and eating at buffets is a favorite activity of all fat people.
