What's the biggest mind fuck or plot twist you've given someone who was judging/harassing you?

I had a girl in my class who was crushing on me and bullying me at the same time (Real weird combo I know) and she could say very rude things just to make me feel bad. She also pushed me down the concrete stairs outside once completely unprovoked. I hadn't even said a word to her.

One day in class she said out loud "You're such a fucking weirdo!"
And waited for my tears.
I responded: "Aaawwwh thank you 🥰" and hugged her. She completely froze. She was in shock.

Everyone who saw it giggled at her.

She didn't try anything with me since.
