Passing on the shoulder when a car ahead is making a left turn on a one lane road. Most commonly seen in the state of Maryland, known as the home to America's worst drivers. Considered a symptom of constant unnecessary overly aggressive driving seen in most Marylanders.
Tom: Shit, the car ahead of me is making a left turn and I don't feel like slowing down.

Dave: I hate Maryland.
Tom: Not as much as I hate New Jersey.
