TITLE: TIFU by fighting too well.
POST: Last night at a Martial arts class. Practicing our grappling, me and another guy squared off. I managed to get in close enough to hip throw him, he landed on his back with me on top of him. We scrambled and I ended up taking his back. I got my legs hooked around his and snuck in a rear-naked choke. He somehow managed to stand up with me still on his back. 

Then he blacked out with 155 lbs of me on his back. He fell and I landed awkwardly on my neck. Now it hurts, I'm icing it, and I'm probably gonna have to miss a few classes now...
TL;DR: 
I choked out my partner in martial arts grappling while he was standing. He fell, I landed on my neck, and I'm contemplating going to the hospital
