piggyback-plowing
Refers to what you request when you hurry over to a neighboring property where someone with a plow-equipped 4X4 is clearing out the homeowner's driveway; you schuper-schweetly ask if he would please come by afterwards and plow you out, too, since he's in your area, anyway.
Requesting piggyback-plowing is often a great way to save big bucks on winter snow-removal, as opposed to having someone actually make a special trip to drive several miles to your house to plow you out; if da task involves just maybe one to three "sweeps", da truck-driver may even do it for free.
