I never really beat anyone up i used to always get the upper hand because I was a big and strong kid. I usually let them go crying home to mommy without denting them too badly. I don't really get into fights.even big guys tend to back down because they think I'm psycho..cause I usually go pretty nuts.
One time a guy did punch me full-force, square in the face because I wasn't expecting it. I didn't really move I smiled and laughed and he ran off before I could get ahold of him. That's the only time anyone got the upper hand on me. As Nowhereman said unles there's a gang of people on you most intelligent people back off.
