A boring looking mini-van, station wagon or SUV used mostly to acquire groceries for the household to transport kids around town. Usually a grocery-getter vehicle is driven, unfortunatley, by a pill-popping soccer mom and/or bored housewife in a loveless marriage. Grocery-getter vehicles are generally not very sexy looking and are selected for their practical utility like transporting spoiled kids, various equipment and groceries of course.
"Her husband bought her a real grocery-getter didn't he?"
"What is up with Anne-Marie? She was zipping around in her grocery-getter all jacked up on something this morning... nearly ran me over, dammit!"
Used car sales guy: So we have a nice selection of mini-vans and station wagons over here you might like in your price range.
Woman: Those are alright I guess. Ooh, I like that silver Toyota Sienna! Can I test drive it?
Guy: Sure...a more fancy grocery-getter if you will.
Woman: Uh, yeah (rolls eyes and sighs). You know I'm not a mom and I'm not married Mr. um...
Guy: Just call me Larry.
Woman: Right. On this test drive try not to talk. You already put your foot in your mouth as it is.
