A game played only when a member of the female class is in her menstraul cycle. The said female gets naked and runs around on her hands and knees. The "cat" who can be a member of either sex, also gets naked and chases the female around on their hands and knees. Upon catching the female, the "cat" removes the tampon from the female, and swings it around and plays with it like a cat does with a bloody mouse.
We cant have sex cause of that? Well shit, lets play cat and mouse.
