The best shade is when you can't discern it from a friendly comment

For years, I was never sure if we were friends or not," Taylor reflected. "She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'"
I think it was patronizing shade. Katy probably heard from her team that one of her biggest competitor's single isn't doing too well. It was also a jab because a Gaga obsessed fan was tweeting her.
