ignosecond 

1) The moment of clarity just after a boneheaded act, but just before the point of no return, when you realize you've just done something stupid.

In the brief ignosecond after the car door left Jeremy's hand, he realized he'd left his keys in the ignition.

ignisecond 

That moment of time when you hear the car door click locked and realizing your keys are still in the ignition.

At that exact ignisecond I knew I was going to be late for work.
