It is a blood choke. The top guy traps the bottom guys arm over his head and then reach as far as he can under the bottom guys neck while driving the same shoulder down into the neck and it cuts off the blood supply. It usually doesnt work because the bottom guy just has to let go of the top guys head to get out of it. But weedman has had his arm stuck.
Oh, I see. The angle they had wasn't that great.
That's the first time I've seen that submission. Seems like it's a tough submission to get yourself caught in.
