the pile of snow left on top of a car after the owner(s) have cleared the windows off. This pile of snow closely resembles a mattress on top of the car and sits in the same place as a mattress would.
This pile of snow is usually left on the car by incompetent assholes who don't understand that when the snow falls off it could hurt someone.

This term refers to African Americans in urban areas who can quite frequently be seen driving around with mattresses tied to the roofs of their cars, due to the fact they move several times a year. This is a common sight around urban areas. Mattresses are often very poorly tied with inferior rope, and additional support is provided by a series of arms sticking out the windows holding the mattresses in place.
I was late for work this morning because there was a car full of Mattress Movers doing 45mph in the center lane.
