The Big Three
Sun, moon, and rising signs โ the modern astrology personality shorthand.
Origin
In Western astrology, your sun sign is the famous one (your birthday's zodiac). Your moon sign is read as your inner emotional life; your rising (or ascendant) is how you present to the world. The trio became the standard 'tell me about yourself' format on apps like Co-Star and The Pattern in the late 2010s.
Modern usage
A dating-app and group-chat shibboleth. 'What's your big three?' is now a recognizable opening line, said with varying levels of irony.
