Slut: A girl who sleeps around more than you do.
Compare with
prude or frigid bitch: Someone who sleeps around less than you do.
This is similar to "dangerous nut
case driver" = someone who drives faster than you, and "slowpoke" = someone who drives slower than you,
maybe even under the speed limit.
It's all where you sit, er, lie.
What a slut! That's the third
guy she's done it with this month.
What a prude (a.k.a. "frigid bitch")! She's only done it with, like, one
guy this year, and she probably wouldn't even go down on him.
or
Oh my god! Did you see the way that dangerous
nut passed us on the blind curve?
I wish they'd get these slowpoke geezers off the road.
