The Ignosecond is roughly defined as the time between the moment one does something inherently stupid and the moment one realizes that it’s too late to stop the results of that action.

Example: You exit your car, lock the car door and swing it shut; immediately before the car door latches you realize that your keys are still in the ignition. That minuscule span of time is called the Ignosecond.

Underrated comedian Rich Hall coined the term “Sniglet” for something that ought to have a word to describe it but doesn’t. “Ignosecond” is such a word.

Because of the instantaneous nature of the Ignosecond, it’s very difficult to capture the image precisely when it occurs. The image above is a great example of a pre-ignosecond, at least for someone; as for the rest of us, here’s The Overnight Open Thread.
