Not everything is for everybody, as this guy seems to be figuring out in real time as his coach goes into just a little too much detail, and is just a little too happy to talk about a certain part of grappling. That's right, grabbing people by the bum.

The look on this guy's face is priceless as we can see him wondering just how extensively he agreed to be a part of this demonstration, and with the lust on the face of his coach, he has a right to worry. The coach talks about being able to control a man by grabbing them in that certain spot, and describes a time he thinks an opponent "lost some rings" up there. We admire this coaches dedication to his craft, but perhaps he needs to tone that butt grabbing down a bit. Or, you know, get in a room instead of ring with his next opponent if he really wants a handful.
