Milk Sisters

When two gay guys have had intercourse with the same guy, they become "milk sisters''.
Guy #1: I went home with a guy from the bar last night.
Guy #2: Ooh guuurl you slut. Was he cute? What's his name?
Guy #1: You know it! His name's Johnny.
Guy #2: Is he blond? Johnny... Johnny Smith?
Guy #1: Yeah....
Guy #2: Gimme a hug guuurll. We are official milk sisters.

bridge sister

(incorrectly called Quarter Sister) The half sister of your half brother or half sister.
Sally is my bridge sister. She is not my blood sister at all. See, my half sister Brenda and I have the same father. Brenda and Sally have the same mother. So, Sally & I are kind of related through our half sister Brenda.

Sister Sarah

An ethnically, as well as religiously, non-Jewish female who either converts to Judaism or immigrates to Israel in order to prosper socially, as well as economically, by way of social networking and unscrupulous political behavior.

For the male counterpart of this definition, please see “Brother Ishmael”.
The woman certainly played the part, she had the yamika and began speaking yiddish. Some say "if it walks like a duck and it talks like a duck, then" you know. But still I just couldn't shake the feeling that this social climber was a Sister Sarah, an imposter.
