A cinematic technique that uses misdirection to lead to an ending that is at first glance completely unexpected or contradictory, but is coherent and reasonable given hindsight and careful observation of the clues presented.

Classic examples include “Memento”, “The Usual Suspects”, "Fight Club", and “The Sixth Sense”.

A process of raping your intelligence; never accompanied by a pre-lubricant; doesn't leave you with an endorphine high and craving a peanutbutter and jelly sandwich or a cigarette. Rarely are dinner and drinks bought for you before or after the act; most often tried on an unsuspecting victim,penetration has less friction; the perpetrator will rarely call you the next day; A passive-agressive way to get their money shot, no happy ending for you.
I just read The New York Times and watched 2 hours of Fox news, now I don't know which hand to wipe with...what a mindfuck.
