Personally I don't think fighting is the smartest way to go about issues. Then again, beating the shit out of them is good too. I think im 6'1" and like 170-180, I can EASILY beat this shit out of anyone. Good advice from that boxer, although my knuckles are huge it still hurts like a bitch when you punch them in the skull. I suggest right under the ribs and into the stomach if you can, it will knock the wind out of them for about 5 - 15 seconds. If your are losing, make fist and point the middle joint in your middle finger out and punch him right in the adamsapple, it hurts SO bad.
If people call you something you aren't set them straight, but if they call you something you are it's not their fault for calling you that since that's what you are lol. BTW, DON'T get a crowd, witnesses fuck stuff up, just do it in some place where alot of people aren't.. Well, unless you want to get suspened for fighting idk nor do I care.
