When one reaches a level of obesity to the extent that he/she has two asses - a fully functional rear ass as well as a non-functional, for appearances only frontal ass.
The frontal ass is anatomically referenced as the Front Ass. The front ass encompasses the lower abdominal area from the pubic bone to the waist line.
"Jabba's getting rather large That's quite the front ass that she's packing. Although I must say, it does help to balance out her rather generous rear ass."
