Stall Sisters 

Ones (usually always girls) who may, or may have sexual encounters in a public - bathroom stall or public bathroom, in a public place. They do this because: they probably don't have any where else to go; it could be the quickest place to go at that time. Or their just that much of a dirty slut (smut), that they just have to "get it in", & it doesn't obviously matter where they have sex; as long as they get it over with.

Girl: "Whatever, they're Stall Sisters anyway. (;"
Girl's Bestfriend: "Oh, yeah ? Haha, whats that ?"
Girl: "Loretta fucked in a b-stall. Elaina looks like she was born in one. & Lacey smells like one. Therefore, they're Stall Sisters !"
Girl's Bestfriend: "Lmfaaaao !!!"

It’s a younger sister that stays the same age and you grow up with out them because they died.

only reason I’m still here is so my sister doesn’t have to go through this and have a small sister forever
