A woman's excuse for acting like a bitch, but an insult when accusing them for having it.
During these times where they become Ultra Bitch, they will: consume random things and people, eyes will turn blood red, mouths will foam, talons will grow, show their hatred for man, and wreak havoc for the sake of 'they can' because it is considered an excuse. Women will scream, growl, snarl, bark and possibly devour you whole, and say "sorry I have PMS" afterwards.

CAUTION: Stay away from all women with PMS, if you hear a growl... run. Run as far as you can.
guy: "Hey wassup?"
girl: *ROOOOOAAAR*
guy: "Oh God! She's infected!"
girl: *chases boy and eats him whole*
guy: *dead*
girl: "I'm f*^%ing sorry I have PMS"

1) Women: Pre-menstral syndrome

2) Men: Pre-maturity syndrome

Both cases can cause extreme irritation to the opposite gender, and are often to blame for disagreements between a male and female.
1) Dude! It must be her time of month, she's got a severe case of PMS!

2) Susan: Just ignore him, Tanya. He's just got a case of male PMS.

Tanya: What's that?

Susan: Pre-maturity Syndrome :D

When a woman turns into a fucking crazy bitch that men will never understand. Also when a woman shows her true personality . At this time women will have an extremely bloody toilet.
This is what happens when a bitch is having her PMS period.

Girl: Fuck off you cunt! I hate you now!
Boy:What the fuck is wrong with you?
Girl: It's all you you CUNT!
Boy: What the fuck bitch?
Girl: I'm dumping YOU!
Boy: NO bitch I dump YOU!

one week later
Girl: I'm sorry for what I did... fuck me
Boy: Fuck off you dumb bitch, you ain't a shit.
