A family I know uses the term "riding the tractor" or shortened to just "tractor" for those in the know. Evidently the family patriarch used to go out in the field and ride his tractor for no apparent reason when they were kids, and they learned what he was actually doing when they got older. Now the grown kids and parents and in-laws all talk about riding the tractor. They all smoke, two generations of family with the third coming up now.
