talk to the jazz hand
A phrase conveying "I don't want to hear what you have to say" Only with jazz hands (a little shake at the wrist) the user is adding a little emphasis.
Girl1: He was like all trying to talk about his new girlfriend when I ran into him.
Girl2: Wha'd he say?
Girl1: I donno and I don't care. I was all . . . talk to the jazz hand about that nonsense. (Gesturing with an outstretched palm with a slight wiggle to the hand)
Girl2: You go sister!
Girl2: Wha'd he say?
Girl1: I donno and I don't care. I was all . . . talk to the jazz hand about that nonsense. (Gesturing with an outstretched palm with a slight wiggle to the hand)
Girl2: You go sister!
