The transformation of woman to
beast, occurring once every month. Similar to the
werewolf, a PMSing woman becomes a dog-like
creature capable only of eating, sleeping, barking, annoying the neighbors, and leaving messes that she expects you to clean up.
Adam probably accepted the forbidden
fruit from
Eve, because she was premenstral. Can't say I blame him; I'd choose the wrath of God over a woman with PMS any old
day.
