something really stupid that most girls and some boys get. it lasts for most of a persons life, and it sucks. they usually ruin underwear and clothes. usually get it every month for like 3-8 days. oh ya, and you get killer cramps. oh ya, and just because a girl is angry doesn’t mean she’s on her period.

The time ofor the month when you shouldn't mess with a girl, ask if she's on her period if she's crying or basically do anything otherwise it will annoy her and she will fucking fight you.
James: "Are you on your period?"
Amanda: "Oh, is it because im sad? JAMES SHUT UP YOUR SO STUPID!"
James: "It was just a question!"

women grow penises every month, it's highly recommended for them to chop them off in order to prevent infection. when they cut them off, they bleed, this is a period aka female menstrual cycle
