A dirt trailer a white trash dwelling which is place on refuse heap. The property is never mowed because the toothless wonders that live in such a place cannot afford a lawnmower. Dirt trailers are usually found in bunches. A rule of thumb is that if you see one dirt trailer in a town, there will inevitably be another one on the horizon.
Jeff: Yo buck, how many dirt trailers have you counted in this one whore town?
Buck: I think we are up to 59 dirt trailers, but i am yet to see one dirt trailer owner.
