This looks like it happened somewhere in Africa. I don’t have any backinfo, so I’m just guessing.
It seems to be a video of a guy dancing on the street as if he liked cock up his ass. Meanwhile, a van U-turning in the background apparently cuts off a motorcyclist who crashes square into its side. Or maybe the biker simply has reflexes of a sloth.
The impact and the landing the biker’s limp body performs are quite poetic. You could almost listen to Tchaikovsky’s Swan Lake while watching the sequence.
Props to Best Gore member @kolmogorova for the video:
