I know what you mean bro.
I trained one of my cousins that fought in the local UCE (Ultimate Combat Experience) and cornered his fights. Lots of those guys act like they are so hard. It was pathetic to be honest, some of them. Lots of talking crap behind people's backs, even training partners would say crap against each other when they couldn't hear. Seriously retarded.
My cousin had one training partner who was a friend from high school who fights at 155, my cousin fights at 135, and his friend was talking crap about me and I didn't even know this guy.
