Dude’s reference is the Dudeism

Dudeism is a religion, philosophy, or 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 BCE), blended with concepts from the Ancient Greek philosopher Epicurus (341–270 BCE), and presented in a style as personified by the character of Jeffrey "The Dude" Lebowski, a fictional character. Dudeism has sometimes been regarded as a mock religion due to its use of comedic film references and occasional criticism of religion in its traditional sense but its founder and many adherents take the underlying philosophy seriously. March 6 is the annual sacred high holy day of Dudeism: The Day of the Dude.

The Dudeist belief system is essentially a modernized form of Taoism stripped of all of its metaphysical and medical doctrines. Dudeism advocates and encourages the practice of "going with the flow", "being cool headed", and "taking it easy" in the face of life's difficulties, believing that this is the only way to live in harmony with our inner nature and the challenges of interacting with other people.

It also aims to assuage feelings of inadequacy that arise in societies that place a heavy emphasis on achievement and personal fortune. Consequently, simple everyday pleasures like bathing, bowling, and hanging out with friends are seen as far preferable to the accumulation of wealth and the spending of money as a means to achieve happiness and spiritual fulfillment. As the Dude himself says in the movie: "the dude abides", which essentially just means to keep existing.

Founded in 2005 by Oliver Benjamin, a journalist based in Chiang Mai, Thailand, Dudeism's official organizational name is The Church of the Latter-Day Dude. An estimated 450,000 Dudeist Priests have been ordained worldwide as of May 2017 and marriages have been officiated legally by Dudeist clergy in some US states.
