Why did she call me an idiom?

Man you know how these tricks be judging a brother.

And I ain't one to beat around the bush either. But, I was feeling under the weather, so I was like you know, I don't know where to go tonight so the ball is in your court, and don't sit on the fence about it.

She like, why is you some kind of idiom or something?

Man once in a blue moon, I don't see eye to eye with a woman, but don't call me no idom and ruffle my feathers.
