What is Suicide Door?
1.
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.
If you're going over to my aunt's house, watch out for the suicide door on the third floor.
