Short for pedophile van. A vehicle that looks as if it is used for the illegal transportation of little children. The vehicle is generally (but not limited to), a white ford E-250 with no back windows. Other variations in designs include any large beat up cargo vans with fences in the back, or with "business logos", that try to make viewers not to scrutinize the integrity of this vehicle.
There's no reason for that vehicle to not have windows, it must be a ped van!
