A Chinese burn is a form of extreme torture, if you're a little kid. It consists of grabbing someone's arm and twisting in opposite directions. It might also be usable on chimpanzees, but no human has yet lived to tell if it really worked or not.
Chinese burns have been outlawed by the United Nations, but since everyone ignores that bunch, Chinese burns continue to be used today. They are also called Indian burns, as this was used as a method of torture on Chinese building the transcontinental railroad who were captured by American Indians.
Try it on me and I'm telling Mom.
You might get one here, called in other places, a ban. That one will leave a mark.
