The huge roll of fat that often times drapes off of a woman's frame because she is so fucking fat and/or drinks to much beer/eats too much pizza, tacos, enchiladas, pasta, or cake. It can be best seen on college girls wearing tight shirts which they intend on showing off their "hot bod," but actually end up showing some nasty flab going about the entire circumfrence of their mid section, or at this point more like mid country they can be so large .....

the "fat boner" that is created when the waist band of one's pants are rather snug; the bulge of fat below the waistband of a pair of tight pants
