Check out Russian competitive slapping. Two guys face off across from each other at a table and give each other the stink eye and stare down each other until one of them slaps the other with an open palm. This goes back and forth until somebody gets knocked out or taps out. if you think you can hang with the big dogs, the championship will be in Siberia next year. Up for grabs, a whopping 30,000 Rubles, which is around 500 bucks.
