Dooring is the practice of opening one's door into another parked vehicles side. Practiced mostly by older people, soccer moms and children, it damages the paint on the opposite cars finish. Dooring is a completely unnacepptable practice, and it is best to honk at the idiot next to you whose doing it to your car. An alternate form of dooring, is when an idiot in your own car, opens the door and scrapes off the paint when the door slides of the curb.
The death penalty is unacceptable in modern America, with the exception of people who practice dooring or vandalize other peoples vehicles.
When you and some friends get out of your car, and run over to someone else's car and open all their doors then run back. The more doors and/or a trunk you can open the better. Also the less people in the car to help shut the doors afterwards the better.
We went Dooring at the stoplight to my friends car, forcing him to get out and shut all his doors.
