An act in which an individual slides backwards across the face of another, and ideally, passes gas. Often performed during gay sex, steamrolling can also be used to punish a party-goer who has fallen asleep with shoes on.
"Saurish fell asleep in the chair about an hour ago, when Bix saw that he had his shoes on still, he climbed up on the arms and totally steamrolled him."
