When a simple ass tag is not enough. Used only for asses that are proportionally bigger than the rest of the body. Not to be confused with wide hips or thick thighs (though they may also be present) — the buttocks themselves should be proportionally exaggerated in these cases, protruding significantly backward behind the person.
Note: An ass that only looks larger because the subject is bent over or any ass that is slightly bigger in size than a flat ass or a normal-sized ass doesn't make it "huge". Above all, size matters.
