A psychological condition that occurs a day or two before and/or during menstruation that anyone who's ever lived with a woman for longer than 2 months can confirm is not a myth.

This is a serious phenomenon in which a woman will say things that can irreparably damage a relationship, treat their partner with a disrepect he (or she) hasn't earned, and estrange them from anyone who does not suffer from the condition.
It took me a year to figure out that the times my girlfriend was acting like a nut were the few days before she was on her rag.

Now, she puts her period on the calendar, and I mark the two days prior as PMS times in which I make sure to hang out with my friends in another town. I don't try to argue with her during this time because I can't deal with the enormous logical fallacies that a woman suffering this condition produces.

dude: ite i'm out. cya tomorrow.
chick: you're going to fuck another woman aren't you. AREN'T YOU?!?
dude: yes, that makes sense. see you tomorrow.

Pre-Menstrual Syndrome. What women go through if they aren't pregnant. Women on PMS tend to be bitchy, and angry for no reason. If your friend is on it, RUN FOR YOU LIFE!
There isn't much I envy about gay guys, but at least their boyfriends don't have PMS.

When a woman is going through the pain of one of her internal organs shedding a layer. This may cause her to have a lower tolerance for incompetence and is why pmsing has such negative connotations.
If you happen to be the incompetent dingwad that pissed off a pmsing female, be kind to those around you and don't go off complaining about "how much of a bitch she is".
Caution: if a girl is angry don't just ask her if she is pmsing. Believe it or not that is one of the most infuriating things someone can say. Its like saying she cant be angry. Even if some shit just went down.
Jerry: god Penny why are you so angry? Are you pmsing or something?
Penny: no I'm not pmsing I have a genuine reason to be angry!

Later....
Jerry: oh my god Penny was such a bitch today. She got angry at me for cheating on her. Can you believe it? I bet she was pmsing or something.

Steve: Didn't she say she wasn't? And why wouldn't she get angry? You were being a dingwad.

The thing about pms, is women don't realize they are being bitchy. I don't even know, when I'm acting bitchy when I suffer from PMS. For those who say it's a fact that it doesn't exist, I don't know where you got that information, because it's a lie.
Women think they are being rational, when they are pmsing.

A period (no fun intended) of time during every month, usually spanning between 5 days up to a week, where men are advised to spend their free time in pubs, clubs and other places of social congrigation, simply to avoid the "short fuse" and irrational behavior of his better half (unless he's gay).
