car-farmer

a person who has car parts spread out on their front lawn. The parts are usually old and rusting - they've been there for a while.

Car parts scattered across the yard, as if seeding the small parts to grow into a full automobile.

car parts = seeds
front lawn = earth, soil, etc.
having car parts laying around on your front lawn = *see also "white-trash"

"My neighbor has tons of old rusty car parts sitting on his front lawn... he's such a car-farmer!"

"His car-farming is brining down the property value!"
