What is slang for cat girl?

Excuse me, I was just wondering if you could help me out with a bit of slang terminology. I came across the phrase 'cat girl' recently and I'm having trouble figuring out what it means exactly. Is it a popular term in the cryptocurrency or finance world? Or is it more of a cultural or internet-based slang? I'd appreciate any insights you could provide on its meaning and origins. Thanks in advance!
