Car-wash whip

It requires a [goofy] hold or a [parallel] hold. Be in a [goofy] hold by step 4. Same as whip up to step 4, on 5 don’t do a hook step, do a cross step forward. Then turn counter-clockwise on 6 and do an anchor step 7&8. I think in step 5 you switch hands (from left to right) and bring your right hand to your lower back, signaling her to go back. On step 5 you can give a strong indication for the follower to turn clockwise by putting her left hand on your right hip. Her left hand will collide with your right hip as she steps backwards and your hip will push her arm clockwise.
