Waterwheel Drop

Waterwheel Drop is a technique described with Arm Whip on page 151 of Ring Dream.
It obviously involves Dropping an opponent, while rotating them (like a waterfeel) in the process to disorient them and possibly target specific hit location. The latter can be done with Judo Throw using expanded rules in GURPS Martial Arts.
It is easier to understand by seeing a video of it in action.
This 2016 clip of Billie Kay appears to show an entirely different move going by the same name.
This 2015 montage clarifies that the "waterwheel slam" comes in several variations. This is not to be confused with Slam in GURPS terms (which is more like a "bodycheck") but rather than dropping someone (letting go and letting gravity do all the work) you keep ahold of someone and aid gravity in bringing them down faster using your own bodyweight.
The first example (possibly also called "Alpha Bomb") in this video shows that the image used on page 151 is merely the setup for the slam. It is a grapple on the legs of an opponent where after a Pickup are held behind the grappler in an inverted position, both facing in the same direction
After this setup, a whipping motion is used to throw them forward onto their backs, lying in a supine position.
The first variation involves the attacker dropping into a kneeling position. The "Sitout Waterwheel Drop" involves dropping to a sitting position.
GURPS Martial Arts has a Sacrifice Throw on pg 78-79 which covers dropping to either Kneeling or Lying.
GURPS Martial Arts: Technical Grappling 40 no longer makes it necessary, replacing it with modifiers to the Judo Throw technique using the Changing Posture bonuses.
The "Reverse Waterwheel Slam" involves no whipping motion at all. The target is held in a prone posture overhead and simply dropped in the rear hexes.
The "Inverted Waterwheel Slam" turns the target 180 (they are back to back) so when they are whipped forward it's the front which hits not the back.
The "Sitout Inverted Waterwheel Slam" is just a combo of dropping to sitting on an inverted instead of kneeling per usual.
