It's all contextual, honestly, but here are my impressions of the uh, categories:

Pisces: wishy washy, both sides, indecisive, peacemaker, likes blue stuff

Capricorn: hustle culture, hates fun

Taurus: confident, aggressive, clumsy, bro-ish

I don't have any others on deck without looking them up lol

Edit: oh my god you guys. the magical star-assigned fixed personality is dumb. what's useful is being able to tell Becky to stop being such a Capricorn and come out and party, even if she is a cancer or whatever. it's just a memey way to reference behavioral traits if your friend group already knows what they mean. i don't know how to explain this any better
