Can I pretend to accidentally break my friends tv?
Oh, that is bad. Why would you want to break your friend's TV?
Yes, because my friend was making me watch a stupid horror movie I didn't want to see
That wasn't very nice of them but hopefully  you didn't break it on purpose. If it was an accident that is okay just apologize and move on.
I'm going to live stream me breaking my friends tvs, it's a great idea.
That is a bad idea because you might have to end up paying for the TV. Especially if you plan to live stream it, you will be showing people that you did indeed break it and he can call the police to tell them you destroyed his property. I think you shouldn't break his TV and you need to talk to him about forcing you to watch a movie you didn't want to see.
