Flagday 

1. This is when you moon someone from the front. You flash them your shlong, for what reason? That I don't know.

2. To flash them your penis.

Bro, did you just flagday me? You're a fruit.

Red Flag Day 

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. You may see this act transpire on Facebook with 12 guys asking "what does red flag day mean,'' followed by 37 "likes" on the initial post. The best means of avoiding this outcome is to remain silent and do not (repeat) DO NOT engage in dialog.

Girl 1: Hey youuu, happy Red Flag Day.

Girl 2: God, I know. I just want it to be over!

Guy 1: What red flag day?

Girl 2: You never listen to me, EVER! I'm leaving... ASSHOLE ::slams door::

Guy 1: ...What!? What the hell was that about?
