when us ladies bleed out of our vaginas on a monthly basis. it lasts about a week on average and may cause you to sit at an awkward angle when you're in school.
causes horrid cramps for most girls.
when you hang out with people enough, supposedly you all menstruate at the same time. this is when the crime rate goes up in your neighborhood/area.

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.

A period is a 3-14 day procedure of when the female uterus leaks out blood. Blood. Red blood. They get horrible cramps that feel like you're getting punched in the stomach contentiously without break. You either eat like a hippo or don't eat anything. Period's can rarely cause people to faint and can start from the age of 8-16, the second you finish your period forever you have no way of becoming prego. Sorry not sorry. If you eat like a hippo on your period you shall consume every solid in sight if it's edible. If you have loss of appetite you shall never even want to look at or touch food. If your a mix of both, im super sorry. The female gender during this procedure are moodier then moody margaret. Please beware of any females if they show signs of being on they're period. Do not piss them off, argue with them, or disagree. Best be if you leave them in peace or give them chocolate. Thank you.
Don't bother Cassandra, she's on her period and she will either beat or kill you.

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.
Girl in the background: KEVIN WHERE'S MY CHOCOLATE BAR?

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."
