Stake Sisters

Similar to "soul sisters", stake sisters share a deep, unexplainable connection, often about strange, obscure eccentric, or dark subjects, leading them to think their ancestors may have been victims of the witch hunts in Early Modern Europe and Colonial America. Connection to any formal or informal version of witchcraft is not required, simply the type of person whose interests may lie in the spirituality of the natural world or have taken them on a different course than the mainstream.

Esme: Teacups? YES. I saw that on--

Stevie: That mortician's YouTube channel?

Esme: How did you know?

Stevie: We must be stake sisters.

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.
