Male Sister

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.
