An educated high class woman who has expensive taste in the finer things but at the same time she can drop it low at the club and can recite a jcole/drake/kanye west verse in a heartbeat.

Example:

Guy1: Damn she's Fine...Too Fine....Too intimidating...Too expensive. Like AT&T, I can't afford her...

Guy2: Nah, look at that pink Juicy Couture velvet pants she's wearing. She's might be classy...but She's a classy hoodrat.
