I hate it when drivers stop right in front of me in the crosswalk, especially when they see me coming. For a while I used the ol' hood slap, or spit on the car, etc. Never done a butt slide though...One day, I decided that instead of hitting the car, I would go right through the backseat, telling the driver on my way through not to stop in the crosswalk next time.
I've gone through two different backseats now, both women drivers, neither of whom I knew. The looks on their faces were priceless! I have tried to go through about three others, but doors were locked.
