A word used by educated peoples in order to justify a prior act of stupidity.
A Radio DJ comes to work dressed in a hot dog suit. When a listener named Vise Evans sees this on the internet web camera, he calls in to the station.
Vise: Dude, you are a fool for doing that. *Laughs*
Radio DJ: No-ignorance!!
Vise: Okay man, I guess you’re covered.
