I stumbled across the following at-first-glance insane video of a guy defending the rear naked choke by biting. Moreover, he teaches how to prevent the attacker from pulling their arm away when you start biting, so that you can actually deliver damage:
A lot of people, in the comment section, are making fun of him, and certainly not taking the technique seriously. However, after thinking about it for a little bit, and letting the shock (and dark humor) of seeing someone actually teach biting as a self-defense technique wear off, it started to dawn on me that this may actually be a good defense against the rear naked choke in a life-or-death situation.
I won’t comment on it further, because I have very little experience with biting. I’ve personally never seen it attempted in a street fight. Of the illegal techniques, people usually resort to headbutts, strikes to the groin, or hair-pulling. I think that these techniques are illegal in MMA because they are dangerous and have an “aura” of unfairness. Those are precisely the reasons for why they should be used in a self-defense situation. Bottom line is they work.
MMA is a sport with rules that encourages safety of the fighters, as crazy as that might sound. Elite MMA athletes are great fighters. But I don’t think that they are the best street fighters in the world. The game changes drastically when the surface is concrete, no technique is illegal, and at all times your life is on the line. Put another way, it’s no longer a game or sport, and requires a drastically different form of training.
