The term snoopy shuffle is used when you see a dog (more common in little dogs) drag their back two legs across the floor pulling themselves with the front two legs. It basically looks like the dog is preparing for a wheel barrel race. If it is a male dog you can be sure the dog not only is dragging their back legs, but also the satchel area as well.
It also can be done by humans as I used to do it to Paul’s pillows whenever he pissed me off when we lived together at Verchild Street, i.e. when he hid Twix’s under pillows it was as sure as shit snoopy shuffle time.
