The swaying movement that anyone will do while waiting in a line. Includes looking at the gum rack, picking up a magazine, touching all the chocolate bars etc.

Jon was not committed to the line. Instead of being 3 feet in front of the person behind him, he was doing the floaty dance in which he read all the labels on the shampoo bottles, and touched all the tic tacs on the side rack. He even left his shoe in the line and went to walk around for another 19 minutes.
