A car full of the owner’s garbage that hasn’t born properly been disposed of (i.e. candy wrappers, apple cores, baggies lined with residue that once contained food)
The mess that's left when you're finally done working on your car. Consists of the old parts, the packages the new parts came in, greasy rags, and whatever toxic waste you drained out. Often accompained by beer cans and cigarette butts.
