Someone who is doing things expected of a fat person. Not usually an insult, as the fat biffer is almost never a fat person. Usually heard in the south of England. Is said quietly, and never with a tone of shock or surprise. This makes it sound like the fat biffer does this sort of thing all the time, though in truth he rarely does.
