Piece of shit car, truck, or sweet van in the reservation. Usually rusty and has loud exhaust. More than likely if it is a truck will be hauling equally junky motorized toys such as four wheelers (hondas) and old snowmobiles. Free lawn mowers are a prize for the beds of these trucks.
Did you see Tom Zoom's new truck?! Yeah, that thing is a real Res Banger. The bumper fell off when he pulled his blown up el Tigre out of it.
