An old rival from my last trip showed up, he's a brown belt now. He's a terrible partner for drilling... lazy, disinterested and spazzy/violent in rolling. I was rolling with him and he told me you can't crossface in bjj. WTF? Also learned that he broke a white belts arm awhile that tapped and he didn't let go. Anyways, I'm going to shit all over his belt for the rest of my stay here, in doing so I will have to make sure he doesn't get ahold of any limbs.
