menstrual high-five 

Usually initiated by the guy, an act and symbol of relief that one's lady friend is menstruating and thus, not pregnant. For example, if your girlfriend is on an oral contraceptive and you decide to pull the goalie for the season, one may start to worry that the pill may not be 100% effective. In this instance, one is excited when that time of the month comes and upon hearing of Aunt Flow's visit, a menstrual high-five is warranted.

Guy: hey babe, this party blows. Wanna sneak into the laundry room and fuck on their dryer?

Girl: I can't. I got my period this morning...

Guy: Whew! Menstrual high-five!!!

*puts up arm with a Todd-from-Scrubs-like grin*

menstruation 

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!
