I imagine it’s some variant on stupid, powerless youths attempting to substitute brute force and cowardice for their feelings of worthlessness. Coming from a criminal defense lawyer, and some will most assuredly need a criminal defense lawyer if they aren’t killed before reaching that point, please know this:
You will get no sympathy. You will get no admiration. This is a dehumanizing blight, and it will come back to haunt not only those who do it, but as it appears to be a game played (at least for now) by young black men, your age and your race. A lot of people worked very hard to try to end racism, and many died for it. It was not so you could devolve into animals for some sick amusement and pretend machismo.
As much as I hate to put it this way, no one will weep if you do this and terrible harm comes to you. This is about as sick as it gets. Your moment of glory doesn’t make you tough or manly, but a pimple in need of popping, and there will be no shortage of people willing to do so.
And for any others who think this is funny, your encouragement of this disgrace will come back to haunt you as well. Any fool can sucker punch someone. It proves your haters right. That is the only thing this accomplishes. Don’t do it. Don’t tolerate anyone else doing it.
