Makes you regret being a girl. Lasts from three days to a week. You can't swim, have sex, and you can't wear that cute skirt or shorts. Only comes when you aren't pregnant and lasts until menopause. You get pissed off at the slightest things and it feels like Niagara Falls.
Person 1- "SHUT THE HELL UP!"
Person 2- "What did I do?"
Person 1- "Nothing, I just got my period, so no sex, swimming or shorts."
Person 2- "oh. Well at least your not pregnant!"
Person 1- "yea, but I gotta deal with this until menopause."

Another way of saying of saying thats on god or this is my definitive final say on the matter. Usually used to reinforce how serious the statement is.
We all need to start acting more like adults starting today and that’s on period.

Mindy should mind her own fucking business, that’s on period.

Flawed.

Once a girl reaches puberty, these hormones take over and she starts to have boobs, curves, and becomes more emotional and feminine etc. These hormones also enlarge her hips and uterus. This lining builds up in the uterus and sheds itself every 28 days if she doesn't get knocked up, thus she gets her period.

People tell me, "Well we have periods because we're supposed to have babies!" But even if this were true, I read this study that a woman ovulates 400 eggs in her lifetime. Who could actually have 400 kids? Even in the old days when they had like 12 kids and they only lived to be like 60, a woman would still have more periods and pain than she would kids.

Now it's the 2000s and nobody has 12 kids anymore, some people don't even like or want kids, but we're still stuck with periods and the average age of menarche is declining due to all the calories and stress. As a result, we've suffered too much from periods: we miss school, lose blood, have cramps, waste money buying "feminine hygiene" products, and basically go through a lot more than the guys do.
Periods are flawed.
They were always flawed, even in the ancient days.
Too much blood loss and waste.

Picture this.... You are a 17 year old girl. You go to school with some bitchy ass preps, your ex, and one friend who you actually see around the school on a daily basis. You bleed through your pants without a change in clothes, you have stomach cramps all day, and people were embarrassed to be seen with you because you look like shit. You go home needing someone to understand you, waterproof mascara, new pants and a damn Hershey bar. This goes on for 6 more days
Guy 1: How'd you get that black eye?
Guy 2: Girlfriend's on her period, she threw a brush at me.
