The girl who will sleep with you if you get her drunk or high, almost like a prostitute, but there's no cash involved. She just likes to party and will use sex as an incentive to get there. She may or may not actually enjoy the sex. It's the intoxication that's important, and the fact that someone else is buying.
"Ah, man! I got such a great blowjob last night from that Good Time Jenny we met at the bar. She was just bad-ass at it, a blowjob ninja, and all I had to do was buy her a case of beer."

"Shit. I'm so bored. I just wanna get totally wasted tonight. But I got no cash. I guess I'm gonna have to pull a Good Time Jenny again."
