Period Pants were invented at the turn of the century as more and more women demanded to be let out of the house while their vaginas were bleeding profusely. In 1896, the United States Congress passed the "Period Pants Law", which allowed women to enter public buildings, so long as they wore designated "period pants" so that everyone knew these whores were out fucking around when they should be at home bleeding into their underwear and girdles.
