Suicide doors refer to car doors that open in the opposite of the regular direction - hinges are at the back and the front of the door opens. Many cars before WWII had those and now it is a popular conversion on tuned trucks. Suicide doors are considered far more dangerous than normal doors because of the possiblity of opening during movement.

Automotive doors that hinge from the rear edge of the door instead of the leading edge. They acquired the "suicide" nickname due to the fact that if the door was not fully closed and the occupant tried to open and reclose the door while the car was moving (which for some reason was once common practice), the rushing air would catch the door and pull it open violently, often pulling the person still holding the door handle out of the car.
Grandpa told us that Uncle Wilbur was run over after he tried to shut the suicide doors on his 33 coupe and was thrown out under a truck. He was never the same after that.

The act of rolling your shorts into a thong and placing your nuts out of the right side and the ween out of the left side to portray the appearance of a Lamborghini with suicide doors.
Bro, stunt on them; and hit 'em with the suicide doors!

A four-door car with rear doors that are hinged in reverse.
The Lincoln Contintals of 1961 - 1970, the new Rolls-Royce Phantom, and the upcoming Lincoln Continental retro car (yes, you read that right).

Doors such as those on pickups, the Honda Element, etc. that are double and open in opposite directions. So called because of the supposed danger of falling out while the vehicle is in motion.
I tried to open the suicide doors on my Element while it was on the Golden Gate Bridge.
