Dudeism is a philosophy and lifestyle inspired by "The Dude", the protagonist of the Coen Brothers' 1998 film The Big Lebowski. Dudeism's stated primary objective is to promote a modern form of Chinese Taoism, outlined in Tao Te Ching by Laozi (6th century BC), blended with concepts by the Ancient Greek philosopher Epicurus (341–270 BC), and presented in a style as personified by the character of Jeffrey "The Dude" Lebowski, a fictional character portrayed by Jeff Bridges in the film. Dudeism has sometimes been regarded as a mock religion, though its founder and many adherents regard it seriously. Dudeists regard "dude" as a gender-neutral word. March 6 is the annual sacred high holy day of Dudeism: The Day of the Dude.
