I am looking for a word or expression (if it exists) describing the movement that a plate makes when you lift from two nearby points of the edge, and then you release one a bit before the other. It looks like a rotation, but it is not.
When this movement is done with the hips, apparently it is called a hip roll: https://www.youtube.com/watch?v=s5Btyc_io4U
However, none of the definitions of "roll", such as "move in a particular direction by turning over and over on an axis" seem to fit the movement I describe.
The closest I can come up is rotational wave but it sounds very technical and I am trying to use this word in a literary context.
