When you're hitting it doggy style and you pull outta hole 1, ram it into her brown eye, punch her in the back, call her by her sisters name, grab her hair and hold on for dear life while squeeling like a pig.
Term used to define the rifle racks people with pickups used to have in the 70-80's in their back windows that displayed their weapons. At the end of the movie "Easy Rider" a guy driving in a pickup passed Dennis Hopper , pulled his shotgun out of his rifle rack and shot him dead.
Did you see the nice weapons in his easy rider rifle rack?
