Get the PM mug.
A word used to describe an extremely scummy person or object. PM is mostly synonymous with siclid. Can be used as a verb. When someone does something extremely scummy, it's called "pulling a PM." PM is always hurtful. In order to be called a PM you have to be one of the scummiest people ever. In order to qualify as a PM, you must have already qualified as a siclid.
Example 1:

Person A: "You are such a PM!"

Person B: "ppreciate that insult, pal."

Example 2:

Person A: "Stop pulling a PM over there, you siclid."

Person B: *cries self to sleep*

Get the PM mug.
An attractive person. i.e. someone you'd go home with before you get too sauced to care. The other end of the scale is a 4 AM, which is reserved for the last-chance stragglers.
"You gonna rock that beauty?"
"I'm buying her snacks, Broseph--that one's a PM"

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.

Get the PMS mug.
A powerful spell that women are put under about once every month, which gives them the strength of an ox, the stability of a Window's OS, and the scream of a banshee. Basically, man's worst nightmare.

PMS (Pre-Menstrual Syndrome) or PMS-ing (Verb) has a wide array of symptoms but happens typically one to two weeks before someone’s period. As someone who gets periods and is probably PMS-ing right now, I want to tell people who don’t experience PMS that we cannot control how angry, sad, happy etc we get so please try to be understanding as we don’t mean to be mean and it’s hard for us. Of course you don’t have to go all out but just being willing to listen is enough.
Friend: Hey, are you okay?
“Yeah, I’m just PMS-ing”
Friend: Oh well it’s okay, I’m here if you wanna talk!
