I'm not mad at it

A phrase used when one is open to or intrigued by something. A: "What do you think of this dress?" B: "Ooh, I'm not mad at it. Maybe in a different color though." My favorite character currently has three different men pursuing her, and while I don't want her to end up with any of them, I'm not mad at it! She should be front and center on this show! A: "I know carrot cake's not your favorite." B: "Yeah, but it's still cake, so I'm not mad at it!"
