The condition in which you think you forgot, or actually forgot, to close something important - your car, front door, stove, etc.
I can't remember if I locked the car. I must be getting Openheimer's.
Damn, I left the car open again. I've got Openheimer's for sure!

When u drop a large poo and the water explodes akin to the mushroom cloud of a nuclear bomb.
Also can be when diareah explodes similar to the impact of the hydrogen bomb
