(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!”
