Have you ever trolled a troll?
My brother did. He was playing Rocket League and one of his team mates that he got for one round was being a jerk during that entire round. After that round, he contacted my brother through the PlayStation network with some insults and my brothers responses to those insults were hilarious. My brother showed me some of his responses to that troll. So, yup, my brother trolled a troll on PlayStation network and the troll just gave up and stopped responding.
PlayStation chat...not PlayStation network.
