When a girl jacks a guy off so hard that he cums blood.
As Maggie was stroking Mat's penis she jumped up in horror once she witnessed his men-struation all over her hand.

A process which happens every month to females and involves discharging the blood and other substances lining the womb, through the vagina. Lasts for 5 - 7 days. Can lead to uncomfortable situations if it begins in a public place, such as school and there's no tampons or pads on hand.

A common misconception regarding menstruation is that all females become moody and psycho during that time of the month. This is untrue. Not everyone suffers from PMS. It is also something that is not to be taken lightly if one DOES suffer from overbearing PMS.

Other things that can occur druing menstruation:
- cramps (abdominal pain)
- tender/sore breasts

Menstruation occurs throughout the majority of a female's lifetime, starting at puberty and ends with the onset of menopause.
When a female begins menstruating, it is cause for either celebration or lamentation.

Hey Chelsea! Guess what? My first menstruation cycle began last night!
