Duncan

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.

The square root of awesome = Duncan.

The square root of Duncan = awesome.

The Duncan 

From the historical account of the St. Louis Cardinals outfielder, Chris Duncan, who makes it a habit of having anal sex and then spinning the girl around to ejaculate in her face.

That girl that I hooked up with last night was dirty, so I gave her The Duncan. She used my bath towel to wipe of her face.

Iain Duncan Smith 

One time leader of the British Conservative Party - in which capacity he proved completely useless. Now he's back in the cabinet taking a big knife to the welfare system. Iain Duncan Smith is bald, rich and a cunt. He lives in his London home rent free. He has never been poor but he's determined to starve out the UK underclass (who were once a working class until Thatcher made them all unemployed in the 1980s). This bald-headed, self-righteous, upper-class, out of touch, money hoarding, benefit cutting, wankstain is also a very boring man by all accounts.

Benfit Claimant 1: You going Christmas shopping this afternoon?
Benefit Claimant 2: You're fucking joking right? All I've got to look forward to is Iain Duncan Smith cutting my unemployment peanuts off. Cunt!

The Duncan Theory 

The phenomenon that causes females to be inexplicably attracted to a random male, like moths to a flame. The art of seduction, commonly referred to as "The Duncan theory'', can have a tremendous effect on the victim.

Also known as "The Duncan Theorem"
The inexplicable phenomenon that causes females to be drawn to a single male (The Duncan) in droves.

The strength at which females are attracted is equal to the grade of symmetry of his face multiplied by the pitch of his voice, and reversed to his age divided by the concentration of his natural pheromones.

I lost my gf due to some guy named Duncan. I swear he just looked at her and she instantaneously became overwhelmingly wet... Hashtag The Duncan Theory

That new Duncan kid looked at me today, I felt a strong magnetic force pulling me closer to him, as my knickers got wet, he spoke "Hey Jenny" ... I swear to god I almost exploded #TheDuncanTheory
