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.
God damn, man,on the bag system, Chloe is without a doubt a three-bagger, that bitch is hideous!
