The Calgary Shuffle is a redundant, hazardous, but amusing move when someone changes lanes, usually without indicating, and then changing back to the same lane within a short period for no apparent reason. This also applies to someone who is bad at shuffling cards or when a person backtracks because they were going in the wrong direction or changed their mind such as in a competitive game.
Traffic is crazy today, everyone is doing the Calgary Shuffle.
