Four fine 

When a girl is so fine that she is beyond "too fine" (usually, about two beyond too fine).

Joe told us his girlfriend was four fine, but she wasn't even too fine. I'd say maybe .3 fine.

Fournine

A fournine is someone that you believe could be a snitch, or possibly an informant. Not a cop, but might as well be. Historically people would holler "5-0h", as an alert when police were in the area.

Typically when a person thinks someone is sus they call out, "fournine!"

Hey, put it away, four-nine in the room.
