You are a fucking loser.
So what if he wore a dress, it was probably just for a laugh. And unlike you he's probably very sure of his sexuality. Doesn't have to act like an arrogant little bully, throwing your fat arse around to prove how much of a man you are.
I also box and part of boxing is discipline which your story proves you have none off. I'm only 5"8 but I way 65kg, whatever that is and pounds, and I guarantee anyone of your weight would be fucking knackered in 2 rounds.
To me your story also seems bullshit and the reason you posted was because you're showing off.
I used to do dumb things like this at school too, but I was very Immature, however I never physically bullied anyone, except bullies like you. Which is what you need, then maybe you wouldn't do it no more.
You're like the fat kid who bullies people at school, but hopefully in about 5 years your class mates will have filled out and will see you in a pub and "bitch slap" you. Or maybe you will "bow down".
And I'll end like I started, You are a fucking loser.
