Period Mania

The scientifically proven phenomenon where women, who live and spend time together frequently, develop similar menstrual cycles as each other. The cause is yet to be determined.

Those girls are so close, I hear they have period mania.

period plug

It's self explanatory. Slang for tampon.

It was the time of the month and Wendy started to drip so she used a period plug.

Period mix

A mix of songs, either a tape or CD, to help your girlfriend or a female friend feel better while she is on her period.

From the movie "No Strings Attached" (2011)

Adam: I understand what's going on. You're all on the same cycle. This is very exciting. Your uterine walls will be shedding for the next three to five days.
Shira: Nice memorization. Did you Google that?
Adam: I may have. Because you're women. And I think that's a beautiful thing. Oh...
(takes out a CD)
Adam: I also made you this.
(hands it to Emma)
Adam: To help soothe your womb.
Patrice: It's a mix!..."Even Flow." "Red, Red Wine."
Shira: "Sunday Bloody Sunday"?
Emma: Adam. You made me... a period mix?
Guy: That's so romantic!
Patrice: Frank Sinatra, "I've Got the World on a String"!
Adam: That's the doozy.

Period shit

The dump a female takes not because she actually has to but because her period makes her need to. This is due to the hormones that signal the release of the lining of the uterus also signalling the gastro system, making the bowels move more.

Jake: "Why did you take so long to get here?! I was waiting forever!"

Tina: "Sorry but I had to take a period shit."

*awkward silence ensues*

Tina: "That's right. You're not getting any tonight."

mouth period

When your lipstick smears out after making out with a guy or girl, therefore leaving the area around your mouth, and potentially his or hers, red. Thus simulating a woman’s period.

I have such mouth period after making out with that hot dude at the bar. Fuck!

Oh my honey, you have a bad case of mouth period. My concealer won’t even help!
