huge ass
Buttocks that are proportionally bigger than the rest of the body. Not to be confused with wide hips or thick thighs — the buttocks themselves should be proportionally exaggerated, protruding significantly behind the person.
An ass that only looks larger because the subject is bent over or any ass that is slightly larger than a flat ass or a normal-sized ass doesn't make it "huge". Above all, size matters.
