My dad taught me the rear naked chokehold when I was little, and it paid dividends in all of those playground wrestling matches that I got into as a kid. The rear naked chokehold originates from Brazilian Jiu-Jitsu, which they call the gentle art, because you can completely control someone without hurting them. Brazilian Jiu-Jitsu is a martial art and combat sport based on ground fighting and submission holds. It focuses on the skill of taking an opponent to the ground, controlling one's opponent, gaining a dominant position, and using a number of techniques to force them into submission via joint locks or chokeholds. I highly recommend that everyone learns the basics of grappling because most fights end up on the ground.
