The Tepee is a alternative to the Triangle submission. As the story goes one of Eddie Bravo's training partners who had short legs came up with this variation while he was training at Eric Paulson's gym. The tekk traveled around until it went back to Eddie. They were calling it the Paulson until the guy that came up with the variation went to train with Eddie again and called it the Tepee.
The reality is that you can call the tekk anything you want. The name is not important but whether it works or not. And the Tepee or whatever you want to call it works. You have to be sure to get the right angles in order to cut off the blood to the head. It's not just all about squeezing hard.
