Supermarket shuffle

The act of two individuals walking head on in a supermarket at which time they are unable to predict the direction the opposite party will maneuver resulting in a left to right or right to left shuffle that leaves both parties felling somewhat awkward about the occurrence. This sometimes leads to nervous laughter or a consequential head on collision.

Ex: Lyle was walking down the frozen foods section at Wally World when in front of him appeared a patron walking in the opposite direction. When the two parties tried to pass they did the supermarket shuffle before bursting into a nervous yet awkward laughter and going on about their business.
