Don't believe this story. A brother in a fraternity would never call it a " frat" that's a disrespectful term. Also a brother would never let one of his brothers go through that shame. They have to uphold the dignity of their fraternity. Now maybe you were T a fraternity party but definitely not a brother.

I'm a little thrown by the fact that his starting point was you having to walk across campus in the nude because someone stole your clothes. How exactly does that count as a stupid thing "you" did? Sounds to me like you weren't given much choice, in that particular case.

id be so mad :/

I would either explain that you don't appreciate those things being told, which actually has worked for me because it made them uncomfortable to be called out on it, or I would embrace it. Depending on the job and my position.

I would explain that friend down and explain you don't want him telling stories like that to coworkers. He must not know how to keep work and a private live separate.

I would honestly tell a few stories I knew about him. Usually that will shit a guy up faster than yanking on his balls.

Do the same to them or make stuff up if they didn't do bad things.
