A girl who is overweight, if not obese, with a short, round build. She rounds out in the belly with small breast, if any at all, formed from excess body fat, packed into too-small a wardrobe. This makes her look like the packaged Butterball turkeys so many of us enjoy over the holidays. Butterball turkeys can often be found basted in their own cheap liquor.
