a paper towel, tissue, pizza box or any other drapery used to keep the lap dry during a road-spank. Typically a hole is punched through the center of the paper towel through which one's member is passed. The user is then free to flog without worry of stained pants, after which the load is wrapped in the smock and discarded at the next rest stop or fast-food restaurant.
On my last drive across Wyoming, I must have burned through 5 cock smocks.
