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.
