The Shyamalan Effect
The feeling of disgust after climax when watching porn. Dubbed "The Shyamalan Effect" because, like M. Knight Shyamalan's movies, masturbation has a mediocre twist ending that makes you question why you wasted time on it.
Some Guy: Yo y'know that feeling when you splooge and like immediately feel gross?
Me, an Intellectual: Ahhh yes.. The Shyamalan Effect.
