An expression used by one of your desperate male friends to describe a girl who didn't tell him to get lost within the first minute of conversation.

As their dry patch goes on, this word increases at a rate of about 4 uses per day i.e. 250 days without sex, and they'll be using this word approx. 1000 times every 24 hours.
Guy : Hi, my name is Guy.
Girl : Cool.
Guy : Do you like stuff?
Girl : Sure
Guy : ...
Girl : I'd better go

*the next morning*

Friend : How'd it go with that girl?
Guy: Man, she's keen!
