They admitted this was a prank. They paid the car guy off. That's everyone laughed, upon my arrival in it.
Basically, a piece of shit car. Usually cheap and/or broken down. Can be any size, make or model, but must (or should) be embarrassing to drive for some reason, such as when you bump the stereo all the plastic "effects" you have hot-glued to the exterior rattle, instantly betraying the cheapness of your bling.
