I've always heard the technique where you hook a leg like that called a "grapevine" I simply shortened it to "double grapes."
Its kind of odd how various techniques are all called different things in different rooms around the country. We used to always joke about that move being called as you all have said the "Saturday Night ride" but technically speaking it was double grapes.
It has always been called a double leg grapevine.

and when you get pinned by it, its "sour grapes"
