Grabing on to the bumper of a stopped car and then haveing them pull you along as they go. This is done only when the streets are ice or snow covered so that the bumperer can just slide along as the car goes.
It was snowing outside so my friend and I went bumpering.

The act of coming up close behind another driver whether one is in a hurry or just trying to be irritating.
That truck is bumpering me! They keep coming up right behind me too close and it makes me angry!
