When a person is too lazy to brush the snow off their car. The result is a trail of snow flying off the back when they drive. Comparing to "Haley's Comet" which a trail of dust and rocks follow it.
Ben: The guy driving in front of me only brushed the snow off his windows and a small section of his windshield. He was a total lazy's comet flying down the highway.
