A friend(no 'benefits') who's so close she's like a sister, or just is the mother of someone who calls you Uncle. (could be a former sexual partner, but who is only a friend now)
How many siblings do you have?
Well, I have 2 brothers, 2 sisters from my mom, & a half brother from my dad, & a courtesy sister I stilll keep in touch with.

The Sinful Sisters, is my joke, on the famous, The Righteous Brothers. They are The Righteous Brothers' biggest rival.
The Sinful Sisters, are a bunch of women, who do horrible stuff, like chaining up, The Righteous Brothers' "Unchained Melody." A joke! Will The Righteous Brothers, free the melody again? Another joke!

A brother who acts more sisterly towards his siblings, i.e. never fights with his siblings, always is nice to them, doesn’t bicker with them, etc.
Friend 1: Have you been to the Wilson’s house? I swear those kids never fight.
Friend 2: Yeah, you’re right. I’ve never heard Eli Wilson say an unkind word to his sisters.
Friend 1: He acts more like their sister than their brother tbh
Friend 2: Fr. He’s almost like a Male Sister.
