Girl-fast

When a guy abstains from all female company and communication for an extended period of time (usually 30 days).

Sergiu: Hey Joe? you still chatting to Erika?
Joe: Naw man, I've had my fill. I'm on a girl-fast.

fast girl

can be either someone whos a slut( or at least gives the idea that she's easy) and/or a really fast runner
( usually the best is a combination of both, but being more of a flirt than actually putting out)

Fast Girl

A girl who has little ambition in life. One who parties heavily and lacks purpose, job or career goals.

I want to hit it with that fast girl.

No one wants to date a fast girl.
