Here's the setup: a venue is holding a slapping contest. One man slaps his opponent, who comes back with a slap so vicious it leaves him unconscious. It's a slap so intense Marshall Eriksen would be jealous.

We had no idea slapping contests were a thing. Are there referees? Can high-fiving lead to injury? How do you practice?

And while we don't condone slapping of any kind, we do think whoever took this video should be punished in some way for the vertical video. It's 2015. You should know better.
