I've seen this in JJJ. Set-up for Osoto, but then step deeper and and place the back of your hips against the ukes'. Then you basically do an Ogoshi movement and drop them on their head, or flip them all the way to the chet, or if they turn in the air, land them on their side. It puts a lot of stress on uke's spine. What would this be called? (Osoto Goshi, Ura Seoi Nage?) Whould it be legal in Judo? Has it ever been a legit technique? Anyone seen this?
