They guy is a fucking pussy. Pomp almost had him in tears, with words.

Act like you're never heard of him. Use classic bully techniques. He can't defend against that. Find a gay dude to practice your clap backs with. Gays are the best at that, hands down.

Or better yet, fuck his girlfriend. You are way cooler than him. It shouldn't be much of a challenge. Extra point for doing in the butt and, for doing it in his hotel bed.

You will forever have a story about taking his GF back to his house and fucking her in the ass, on HIS couch. He will never be able to look you in the eyes again!
