Used to indicate that one does not want to see, hear, know, or have anything to do with something. Used for comic effect.

Originates from an alleged, bad English-to-Chinese-to-English translation of Star Wars Episode III. In the end, Darth Vader's infamous "NOOOOOOOOOOOOOOOOOOO!" is subtitled "DO NOT WANT!"

A few weeks ago, no one had “cheugy” in their vocabulary . Now everything is saturated with the word. It’s in our heads. It’s in our homes. Everyone is asking: “Am I cheugy? Am I a basic ass bitch? Am I GUILTY of being cheugy?”

The proliferation of cheugy in the mainstream discourse can only be attributed to one source: mental terror. It’s an orchestrated psychological trap to make you question your tastes and interests in the eyes of others.

You are not a cheug. YOU’RE PERFECT!!!!

It is very suspicious that the cheugy mascot is a Minion, a literal cyclops, a deformed
yellow panopticon in overalls ... do not let the all-seeing eye to control you. Be vigilant. Resist cheugy psyops.

Catchphrase popularized on 4Chan, which spread to other various forums online, signifies that the content of a thread isn't desired or liked that much

Acquired from a bootleg camcorder Hong Kong subtitling of the Chinese dub of Star Wars Episode III, in which Darth Vader's howl of 'NOOOOOO!' scream is translated to Chinese and then back to English as 'Do not want'

This is the phrase originally intended for Darth Vader to shout at the end of Star Wars Episode III: Revenge of the Sith. However, shortly before the film's release Lucas decided that a snappier, more effective phrase could be used, such as "NO!"
