PMS 

The mythological belief that before menstruation women all act exactly alike (i.e. all women become evil or irrational). The myth has its roots in reality. Prior to menstruation women may have mood changes due to hormonal imbalance and in reaction to physical discomfort. The myth that all women become other-worldly beings is a result of inherent sexism within society and the male of the species' jealousy of the female's ability to give birth.

Woman: "I am a monster."
Man: "You must be PMSing."

PMS 

Pi ssed off at
M ankind
S yndrome.

Occurs a little before or during a girl's period. It basically makes you feel like crap for anywhere from 2 to 5 days.
Let me put it this way, if men had to deal with this, the international suicide rate would be a lot higher.

It can causes any or many of the following symptoms: mood swings, low self esteem, headaches, cramps from Hell, bloating, snapiness, fatigue, muscle/joint aches, food cravings, heightened thirst, nausea, stomachaches, more frequent crying, insomnia, boob tenderness, acne break outs, or even nightmares.

I don't suggest teasing your girlfriend while she's go through this.

Girls may celebrate its completion with ice cream.

Jeez, PMS blows. This headache's been going on all day!

Dude, don't mess with Stacy right now, she's PMSing. She'll bite your head off!

PMS 

Post Missionary Syndrome. Often times when Mormon boys return from their missions they act and react awkwardly in everyday situations due to their detachment from real life situations for the past two years.

"See that guy over there? He just got home from his mission and he totally has PMS"

"Dude, would you relax around these girls? They're supposed to have the tampons not you. You must have PMS"

PMS 

Pre or Post-Midnight Snack:

It is a humorous term intended to be confused with the scientific Pre-Menstrual Syndrome (the original PMS), especially when used by a male.

Mike: Man, my PMS was really delicious.
Joe: What...?
Mike: My Post-Midnight Snack.
Joe: Wha-? Ohh.

Phil: I think I'll have my PMS soon.
Linda: Jerk! Are you making fun of me?
Phil: What? No! I'm just gonna heat up my Pre-Midnight Snack!
Linda: Hahaha, that's... clever.

PMS 

Former Medical Term, abbreviation for "Premenstrual Syndrome".

A mysogynist term for the combination of
a)hormonal changes a woman undergoes that prepare her to menstruate and
b) the exhaustion caused by women not taking care of themselves at this time.

Often used to exonerate another person of guilt for wrongs they have done to the involved woman by minimising her reactions.

Bill: Jude, why's June crying?
Jude: Oh, I just said her cooking sucks and she needs to clean the house more often. She started crying and yelling about being unappreciated.
Bill: Oh, sounds like she's got PMS.
Jude: You got it, Bill.
