Palestinian Chapstick

A truley romantic sexual act in which a man inserts his penis into a woman's menstruating vagina to have sexual intercourse, and once the male is about to ejaculate he takes out his blood-soaked penis and smears it on the woman's lips.

If the woman does not say "Thank You" afterwards, the man is permitted to drop an anvil on the woman's head from what ever height he so sees fit.
