breezy

Acting cool and aloof so the person you're talking to doesn't think you're trying too hard.

Girl 1: "I hope he doesn't think I'm retarded"
Girl 2: "Don't worry, you were fine. You were totally breezy."

Original reference is from Friends. "Hey, it's Monica. Just calling to say hi. I'm breezy."
Everyone else: "You can't say you're breezy!"
