i think the guy recording is with the guy who attacked the girl, and he is there to record him attempt the knockout(as that is the point of the "game"), so he tells him "lets go" to tell him the camera is ready. But it doesn't go as planned so the camera guy just acts like he wasnt with the guy who assaulted the girl...
Not really related, but still. <iframe width="420" height="315" src="//www.youtube.com/embed/gEyFc6_UNB0" frameborder="0" allowfullscreen></iframe>
In middle school we used to punch each other in the nuts and say grits as we did it. We used to also play open chest. Pretty stupid stuff.
I really wish the media would stop referring to this as a knockout "game". I know the intent is not to trivialize it, but why use a name which connotes that its a fun thing the kids are in to?
It's been going on for a long time, kids just post it on YouTube now. Black boys beating up on White boys, White boys beating up on gays or homeless people.
