The gap that forms between a standing woman's thighs, all the way up to her vagina, when she is anorexic and her pants are tight enough to show it off. So-called because if you turned her upside down, you could place objects on the flat surface directly between her legs, which is also where many women keep their vaginas.
Jesus christ, did you see Cari's vagina shelf? Did her pelvis separate?
