n., a used car gifted to a college student but that formerly belonged to a formerly living relative. Easily recognizable by its vast size and American make. Originated at the University of Virginia in the 90's. Also known as "dead relative", "dead grandpa", or "dead uncle".
Josh, your 1985 Lincoln Town Car is clearly a dead grandma. It takes up 2 spaces in the dorm parking lot and smells of thanatopsis.
