P4P highest concentration of arm punches I've ever seen. Sheeeeesh.
Also, if you're mad enough at someone to actually throw hands (and only hands, lol), why would you embrace afterward? Fighters embrace out of mutual respect after competing. It wasn't personal. But you have to be pretty pissed to street fight someone you don't know. He may be skilled, he may be armed, he may be fucking crazy, he may have sick kids at home who rely on his ability to work etc. If you want to hug and kiss afterward, why not arm wrestle run a race instead?
