A system or nomenclature used for labeling the intensity of ugly a given woman is subject to. A woman can be ugly on one of any three levels. First, the single-bagger, or a woman ugly enough to merit one bag over the head during intercourse; Second, the two-bagger, or a woman who is so ugly that a bag is needed to be put over both her head and yours during intercourse, and finally, the three-bagger; a woman so entirely atrocious that not only do both you and her necessitate bags over your heads during intercourse, but so does anyone who may (god forbid) be looking in through the window.

When someone is sexy by the body but ugly ass fuck in the face, so you use the double bag system. One bag in their head and one bag in yours, just in case theirs falls off.
