curveback
When someone curves somebody else, regrets the decision, attempts to make advances on that person, and in turn gets curved.
Dude 1: I was hitting up this chick, but she was ugly so I curved her.
Dude 2: Yeah man.

Dude 1: I think I'll hit up that chick again, I realize I'm desperate.
Dude 2: You right, I am too.
(One week later)
Dude 1: Damn man, she never responded to me.
Dude 2: Bro, you got hit with the curveback.
