Whack!

The first-ever Russian slapping contest took place over the weekend, where competitors slap each other as hard as they can in order to win.

Known as the “Male Slapping Championships,” which took place in Krasnoyarsk, the rules are self-explanatory: Two men stand opposite of each other before a table. One gets slapped, then the slap is returned. If you can’t continue, you lose.

A viral video of champion Vasiliy Kamotskiy made the biggest noise on social media.

Kamotskiy took home nearly $500 after winning the competition by delivering two monster blows to his opponent. With his first slap, the burly Kamotskiy sent his competitor stumbling backwards, nearly knocking him out.

After he received what appeared to be a misfire, Kamotskiy lined up his next slap, winded his hand back and unleashed an absolutely lethal KO.

The referee called the match within seconds.
