Stomach Sisters 

(Originally an Icelantic term) used for multiple girls who slept with the same person

Girl #1 “Look at this boy that I did it with last night, isn’t he cute?”
Girl #2 “Oh my God, I slept with him too! That means we’re stomach sisters!”
Girl #1 “What does that mean!”
Girl #2 “That means that we’ve slept with the same person!”

sisterfister 

Strictly, one who indulges in a particular form of incest, using only their hand (see fister. Often used as a term of contempt, and shortened to "sissy" on account of their unadventurousness.

See also brotherfucker.

Your brother's such a sisterfister, you know.

Hey Sisters 

Something James Charles says at the beginning of all his videos.
Also what some other people (most likely stan twitter) might say when greeting their fellow sisters (friends).

James Charles: “HEY SISTERS! WELCOME TO ANOTHER SISTER SPECIAL VIDEO! TODAY I’M GOING TO BE SHOWING YOU MY MORPHE KIT!”—— and then he continues to add sister of to everything that starts with an “S”

house sitter 

When you take a massive grommer in someone's toilet and close the lid afterwards while they are away on vacation. Then they come home after a long drive, rush to the toilet, open the seat and BOOM they meet the house sitter.

Did you hear that Amos threw up blood when he met his house sitter after he got back from the beach yesterday?
