I actually know what he means on both points
As a fighter, especially an MMA fighter, you know damn well you have the ability to beat the dog sh*t out of someone. U could violate them. And they can't do anything about it
He probably walks in a boxing gym and sees alot of smaller guys and he's sizing them up.
But also, boxing gyms are toxic as f*ck. You can get bullied and nikkaz will clown you and make u feel soft. No matter how tough you think you are lol
So I guarantee he was humble and quiet than a MFer while he was there
Thinking all that weirdo rape sh*t in his head in the corner somewhere
