i didn't see it as such, seemed like he was trying to get in the middle and protect his gf from getting her ass whooped, then the giant fucker def sucker punched him
Yeah, that's how I saw it, but dude still was "attacking/moving" (try to remember how full of adrenaline these people are) the other dudes lady, so he went crazy on his ass, but 100% sucker punched him like a bitch.
