Mom’s petty and immature boyfriend

r/

For context: I’m an 18 year old woman and I’m seriously done with my mom’s boyfriend. This guy constantly finds something to mock me about whether it’s my workout, my physique, or even making fat jokes about my mom right in front of her. He also had the nerve to accuse me of breaking something just because I was the only one home. He asked how it broke, I said I didn’t know, and this clown starts laughing, trying to indirectly accuse me.

When I finally snapped and told him how insulted I felt, he flipped out. Full-on screaming in my face, acting like I started it. I straight-up told him it’s not that hard to say sorry, he can’t seem to do it because he thinks he’s never wrong. No idiot would be mad if they actually did nothing wrong, but that’s all he knows. I told him whatever unresolved baggage he has with his past family isn’t our problem, and he starts crying about how “his kids don’t talk to him anymore.” Like, no surprise there. Then he pulls the classic “I’m just like this, I can’t change” excuse, as if that makes being a complete asshole okay.

Honestly, I want revenge. Not something illegal, but something that’ll hit him where it hurts his ego, his image, something that’ll annoy the hell out of him without dragging me into trouble. Any ideas? I’m ready to mess with him without actually crossing any lines.
