After having intercourse with a female whom is currently having a menstrual cycle, the male quickly pulls out his penis from the girls vagina and slaps the female in the forehead with his limp penis leaving behind a bloody slap mark, resembling a gunshot wound. Most importantly, the male must exclaim "bang" after he leaves his mark.
