What's the best way you got back a roommate for having loud sex?

So I have mentioned this story before, but my roommate last semester was a man hoe. He would frequently bring girls back to the dorm even though he claimed he had a girlfriend. Anyways one night he brought a girl home who woke me up at 3am by screaming during sex. I consider myself to be a calm reasonable person so I did what any calm reasonable person would do. I got out my phone connected to the Bluetooth speaker in his room and played a video about queefing at max volume. She shut up really quickly and my roommate told me they were so embarrassed they just layed on the bed listening to some girl explain queefs to them for five minutes. I slept like a baby after that.
Edit: I guess I need to clarify that my roommate wasn't actually mad at me. It wasn't the first time he had loud screamy sex in the dorm room and I was getting sick of his **** so that's why I got him back. I ignored it the first couple of times and when it got to be a semi regular occurrence I knew it was time to go nuclear on his ass. Anyway the next day he admitted he deserved it and he would try to be more quite in the future.
