The philosophy of some people called Duncan who believes in everything that is beautiful, wonderful, just, kind, total freedom for anyone who is cool, top quality, the best in the world (or at least close) etc. Duncanists hate and despise anything bad, low quality, ugly, and believe that assholes like that who believe in that shit should spend the rest of eternity in their self-inflicted hell. And we don't care (ref Sex Pistols/Malcolm Maclaren)

Duncan is the smartest person in the world and is sometimes referred to as God of all Mankind. He is insanely funny with a sharp wit. He is abnormally kind and generous. He also has a massive cock that CRUSHES tons of pussy. The vag that he hasn't gotten to pounding yet, desperately yearns for a Duncaning* (verb present participle). He is seriously bad-ass. All men wish to be him except idiots and retards. It's because all idiots and retards wish they were presidents and superheroes. They don't realize that every president and superhero wish they were Duncan. He's probably the best looking human ever born and has won multiple awards for having the best ass. He won the Nobel Peace Prize for having the best ass. Duncan is very successful and has superhuman strength. If you are a stupid asshole motherfucker and Duncan sees you, you should run forever because he cares about humanity and will kill you for the good of the people.
