The act of doing the same thing over and over, expecting different results, much like the Old-School RuneScape user Yx, who is a homophobe and places chairs and rope under lgbt players trying to tell them to kill themselves, and makes jokes about mass shootings.
NutsAndTits: Yx is so mad that they are failing at this. I'll take the free items though.
Rayquazas: Yx, you know the definition of insanity right?
Yx: no what?
Tehnubness: Exactly what you are doing, and failing at.

When criminals plead guilty to a crime of lesser seriousness than what they were convicted of, and afterwards being proud of said fact.
Crime insanity? A perfect example would be a Baltimore man recently convicted of 18 criminal counts including attempted murder and all he got was 6 months or less in jail for some stupid arson charge. This dude is now on tv claiming he shouldn't be out. What crime insanity.
