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.

Get the That’s on period mug.
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.
