1. "A mindfuck is a slang term which describes a work that uses literary devices such as nonlinear storytelling and plot twists in order to present convoluted, yet not conflicting, themes. A creation is usually considered a mindfuck when a casual observer is not able to discern the true meaning of a work without making a serious attempt to unravel the themes presented or when the plot is incredibly difficult to follow. Special examples of mindfucks involve a single plot twist which completely changes the viewer's understanding of the events in a film or novel as well as the ideas it presents." (Wikipedia)
