Some time ago I heard a guy that was into The Game and studied astrology. He had found that every star-sign was related to another star-sign in one way or another. There’s compability, moon date, and a bunch of stuff I don’t remember. The point was that you could always clame you were destined together regardless what star signs you both have.
The idea is to have a handy little app (or website) that you enter your birthdate, to configure it for your star sign. Then you just pull upp the page and ask the person what star sign they have, tap it, and see how you’re connected in the stars!
