vagina sisters

Close friends who have had sex with the same boy. Like vagina cousins, but more important.

Kerri and Christina are the best vagina sisters out there.

sisterly

A friend who displays affection and kindness in a way your own sister would if she really cared about anyone but herself.

Jay was being super sisterly by supporting my decision to get an abortion.

Sister Mama

Two baby mamas who share the same baby daddy. The baby mamas are friends and have good relationships with all their children and each other's families, without the baby daddy.

My baby daddy gets jealous that his two ex's get along and have become Sister Mamas, who act like positive loving adults for the sake of their children.

Sister Twister

When you put your dick in your girls ass, and proceed to spin her like a helicopter blade. Doesn't have to be your sister, but it can be. Works best with small girls as they are easier to spin.

I had a dream last night me and Mila were doing the sister twister when my dad walked in.

An insult that has the same effect as your mom gay.
