Period
A time when a girl bleeds from her vagina, gets cramps and gets in a bad mood. They get in an even worse mood when another girl has their period, but they don't have any cramps or pain.

Some people think it's gross to have sex while a girl is on her period, but period sex is perfectly fine. Some docters actually recommend period sex.

Pills can be taken to reduce the amount of blood a girl has on her period. For girl who can't take those pills? Sorry, you're out of luck.
Girl: FUUUUUCCCKKKK, I HAVE MY PERIOD
Girl 2: I do too, normally I don't get cramps on tho
Girl: Hhhhh-
