Stall Sisters

Ones (usually always girls) who may, or may have sexual encounters in a public - bathroom stall or public bathroom, in a public place. They do this because: they probably don't have any where else to go; it could be the quickest place to go at that time. Or their just that much of a dirty slut (smut), that they just have to "get it in", & it doesn't obviously matter where they have sex; as long as they get it over with.

Girl: "Whatever, they're Stall Sisters anyway. (;"
Girl's Bestfriend: "Oh, yeah ? Haha, whats that ?"
Girl: "Loretta fucked in a b-stall. Elaina looks like she was born in one. & Lacey smells like one. Therefore, they're Stall Sisters !"
Girl's Bestfriend: "Lmfaaaao !!!"

Sister Ex

Your ex's ex with whom you have become friends. The friendship starts out as a trauma bond, swapping stories and comparing notes on the dude's lies, cheating, and manipulative behavior, and evolves into a genuine sisterhood.

I'm getting together with my Sister Ex on his birthday to wish him a year of pain and misery.

My sister ex confirmed he was cheating on her with me when we met.

menstrual sister

one of two (or more) women who happen to fall on the same menstrual cycle. Menstrual sisters often times find comfort in sulking, eating, complaining, and causing a scene together.

My menstrual sister, from the stall next to mine, threw a tampon at me as I kicked my door in anger.

As a good menstrual sister, I shared my chocolate as we bled and weeped together.
