When someone is out of condoms and they don't wanna waste time, they end up "raw dogging the dirt trail," which means to have anal sex in order to prevent pregnancy.
John: Did you get some last night?
Peter: Well, I was out of condoms and didn't want to have a young Pete running around, so I decided to raw dog the dirt trail.
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.
