That weird stumble you make when you are walking with flip flops and the toe part of the footwear bends into the sole,because of how your feet were too close to the ground. Hence, the term is used.

Friend2: Calm down damn it, I almost had a Flip-Flop Shuffle when we were walking down this bumpy-ass sidewalk.
