I've been trying to write the first sentence of this post for a while now and it's just a lot of opening my mouth as if to offer up some kind of context, followed by quickly shaking my head.
These are kids. These are kids on skates absolutely beating the crap out of each other for a solid 2 minutes. At two separate points in time on this video a child flies in the air, tackles another child and continues to beat the crap out of him. Near the end, one kid has another kid pinned down and is wailing on him. The referees appear incapable of tearing these children off one another. There is weird, Russian rap.
If you and Mick Dundee were sitting around discussing youth hockey fights, this is the one Mick Dundee whips out on his smartphone.
