The act of driving so fast that it causes the passenger sitting shotgun to subsequently lose all control of their bowels and/or jam their right foot into the floorboard as they instinctively mash the invisible passenger brake pedal

My friend's new car is so holyshitfast that he needed to get the passenger seat reupholstered after he took Dave for a ride
