This is the only hold on the list that doesn't have any, uh, "additional fun" attached. That kinda speaks to how fun the hold is, though.
For me, I am a chokehold enjoyer. Sure, there's a lot of other holds that are still very fun. It's all about the domination after all, isn't it? Of those, back torture holds are far and away the best. That might be a little obvious from my gallery...
This combines both. She gets an unlimited amount of ways to vary your torture without having to change the hold. If she just wants you to experience agony, all she does is move her arm up slightly to pull back on your chin instead of your neck. If she wants you to go to sleep? Arm goes right around your throat. That means a whole new world of domination. Imagine this- trapped in a camel clutch, slowly being stretched further and further back, pain slowly mounting until it feels like your spine is going to snap. You reach your limit, and you scream or tap your submission.
You get your mercy- but not in the way that you had hoped. She doesn't let go. She just stops leaning further back, holding you there at your absolute limit, and wrapping her arm down around your throat. The pain finally stops when you pass out completely, and wake up back on the ground, still trapped in position for another hold.
Not to mention, in my experience, this hold is the FASTEST knockout in the universe. Once you're wrenched back, that arm around your neck puts you out in not much more than a single second.
