Okay if it's not worth fighting over FIGHT ANYWAY because I once tried to turn away from a fight and nearly got my neck broken
I couldn't walk for two days it hurt so bad.
Okay a sucker punch is if you start the fight by attacking the other guy from behind or from broadside while he's buisy or something.
A perfect example is a friend of mine said he was talking to this one guy's girlfriend and the guy came up and slammed a fist into his back because he thought he was trying to hit on his girl. That is a sucker punch.
And this might just be me but if you get within 18 inches of me and you are looking threatening I'm gonna take you down before you can attack me because if you are within 18 inches and you are looking threatening you can attack before I can react properly. Never let the other guy land a strike first, if you know you can block it or deflect it go ahead and let him throw the first attack so you have the "I was only defending myself" excuse but if you know he can beat you in a square fight and he is coming at you like he is about to start one....take him down first.
