A vagina of the dirtiest kind, often infected with multiple STDs - with a far from pleasant stench. After an encounter within several meters of a 'rotbox'.... the image that springs to mind is that of a witches face - after being violently attacked with an axe.

Her cunt smells sooo bad... Im going to call it a rotbox!
Close your legs Jane!
