Huge Man Gets Completely Knocked Out During A Professional Slap Fight (Video)

Boxing has often been referred to as "the sweet science," a testament to the incredible amount of skill and forethought an athlete must have to perform at the highest levels of the sport.

Slap fighting, on the other hand, doesn't have a glamorous nickname like that because it literally consists of two people facing one another and slapping their opponent until someone decides they're tired of getting hit in the face.

The two "sports" do share one thing in common, however, and that's the potential of a knockout occurring every single time two people square off.

It's not exactly a common outcome, but that doesn't mean it never happens.

Want proof? Hit play.

That should be sufficient evidence.
