Instead of waiting in line for a mile or four at a congested off ramp, driving as close to the junction/barrier to the exit in a faster lane and darting ahead of the lineup when there is a large enough gap created by a transport trucker or typical Houston driver who is distracted by the bowl they are packing with one hand while texting with the other hand.

A perfectly executed Houston shuffle is when the shuffler's vehicle rear does not protrude into the previous lane, they did so without going over a solid white and/or pylons (as 12 sometimes issue tickets solely for poorly executed shuffles), and vehicles behind cannot get offended because after all they created a 4-car-legnth gap ahead of them that was ripe for a Houston shuffle.
