 [ "Red Flag Day" ]

1: 1) Pertains to the marked days of a woman's bleeding "period" within the menstrual cycle, from the beginning to the end. 2) "Happy Red Flag Day" is a phrase often used in woman code to welcome one-another into the relentless, ceremonial unleashing of hell about life's problems, onto the ears of the unwilling-- mainly men.
