look up any word, like donkey punch:
When you KNOW you're in control, but you lose it JUST FOR KICKS
"Kid, you hear about ol' dude gettin' caught runnin naked in the street? Man, he on a whole 'nother level of insanity"

Insanity isn't deciding to do what the sane man does not.
Insanity is when you forget what the sane man does.

insanity.... when you start to talk to your dog, yet not even the dog is listening
you: (walks in, shuts the door) Hey, boy, hows it going? today was the worst day of my life... blah blah blah... well atleast i have someone i can count on and talk to.

dog: (during the whole "conversation") looks the other way after hearing the door open and starts to stare out the window and bark at the bird outside. (ocasionally looking back to see if you are still standing there)

Doing the exact same fucking thing over and over again expecting shit to change, that is the definition of insanity.
"Did I ever tell the definition of insanity?"
Coming to the realization that it really is all in your head, and that you are the master of your own universe.
What is more real than human perception and cognition? Free, honest pure souls are those we say "suffer" from "insanity"

Repeating the same things over and over again and believing that Mickey Mouse is controlling your behavior from the twelfth dimension.
Insane people often define insanity as, "Repeating the same things over and over again and expecting different results". Most of the time insane people don't realize they are insane.
