Suicide door

[Britney]

A car door whose hinge is near the rear of the car rather than near the front of the car. So called because it tends to fly open if caught by the wind (especially in the case of poor panel fit or an open-top car that does not channel air efficiently) rather than shutting right away, causing the car to become unbalanced at speed and leading to numerous other possibly fatal results, such as the car being thrown to one side and crashing or an occupant thrown out of the car.

[Rihanna]

A door in a building on the second floor or higher leading outside that probably had a balcony or porch at one time, but now leads to nowhere. A door like this where there is something soft at the ground to cushion your fall does not count as a suicide door.
