sub roll
The shape given to the area of a woman's panties or thong above the vaginal opening and below the "FUPA" caused by an excess of unmaintained pubic hair. In other words, the excess hair gives rise to the appearance of a sub roll stuck in the woman's panties.
I bent down to help her out, looked up her skirt, and saw that she had a sub roll jammed in her panties with some lettuce pouring out the side.
