According to the backinfo I got, this happened in Ukraine.
The video shows a naked man disrupting traffic on a public road. As he tries to block passing vehicles by standing his exposed private parts in front of them, most drivers maneuver around him and continue on their way.
Eventually, he succeeds in blocking a car driven by a meathead. The meathead get off, appears to say a few words and then throws a punch, knocking the naked guy out.
I’m not sure if the naked guy was on drugs or had a mental health issue.
Props to Best Gore member @missprovacateur for the video:
