Why would anyone want to choke another person with only one hand? Lots of reasons, that's why. Maybe you only have one arm, or maybe your drinking a vanilla latte (or some other kind of latte) or holding a slice of pizza with the other hand. Maybe you are carrying an infant child and need to choke a man unconscious at that precise moment and there is simply no time to hand the child over to another person. Maybe you're texting something important like a well-time LOL, or you're playing Words With Friends (play me: DSTRYR) or posting a photo of your dog on Instagram.
I think we're on the same wavelength. There are many occasions in which you may only have the one arm with which to choke and it's nice to have proper instruction on the matter. Now, watch as Scott "Einstein" Epstein of 10th Planet shows you how to do it, care of RevGear.
