Has anyone heard of a Bridging Doble Reverse chinlock?

I was a scrapper at school. Ive taken hits, whatever. I never threw many hits though. I always grappled. There was a move I discovered, where I put someone in what looks like a chinlock, but they arent face downl, and neither am I It starts like a reverse chinlock, but I use their lack of balance, to pull them on their back. Not to the ground, but they dont have enough leverage to stand either. As I gain more of my leverage they go down further and have less range of motion to manuever with, and there is more tension on the neck. They are basically in a limbo stance, the only thing keeping them up is my arm which is viced to the throat.I have asked all kinds of martial arts sensei what the heck this is, and they didnt teach that specific motion. Is this what its called, and where is it from? A friend told me what it was called, and wondering why nobody ever heard of it? I cnan either roll into a pin, or pivot their neck backwards. Oh, and their face is in my pits. Thats the dangerous part.
