Explosion Door

''Don't open that door! Seriously.''

This is when someone opens a door to a room that's filled to the brim with something and that said something falls onto them. In real life, Explosion Door might be next to impossible, especially when it happens with a water-filled room.

Usually only Played For Laughs, Explosion Door is an exaggerated display of amount of something. As in the amount is so large that it could fill an entire room up to its door.
