The act of opening a water bottle and pouring it out on the side of the car to wash the mud and dirt off while driving down the road. Usually takes more than one water bottle to do the job. Can also be a productive use for water or flavored water that has a horrible taste.
Man me and Billy were out of change for the car-wash so we just used an old water bottle in his car and pulled a Hillbilly Car-wash.
