The action of accidentally turning off the last light in the house (when it's dark outside) resulting in disorientation and/or bumping in to things whilst looking for for another light switch.
Mike: Bro! I was about to go to bed but I accidentally Prematurely De-Illuminated the room and had to use my cell phone as a flashlight!
Brad: Man, I know what you meen. You gotta be careful with that Premature De-Illumination, last night I smashed my foot trying to find the bathroom when I did that.
