The end all be all of all arguments. Doesn’t have a cool down and will completely annihilate your opponent.

The ONLY known technique that is able to free you from the almost-inescapable insult, known as, "ur mom gay lol."

How to use this dreadful counter:

1. Bait your (already dead) opponent into using the one hit one kill insult, "ur mom gay lol."

2. Smile! You've already won. Use the "no u" comeback.

3. Watch your opponent die a horrible death. Don't let children watch, as the violence is too much for young minds.

The universal rebuttal to all arguments.

The end all to any argument. Used when one either has no intelligent argument left, wants to try and use "no u" as an intelligent argument, or want to piss someone off. Most effective after one has been insulted.

Saying NO U is a way of pointing out that the person's comments apply more to himself and is therefore an idiot and a hypocrite. It is considered to be the ultimate trump to any debate or drama on the Internet.

This meme originated on the Something Awful forums where epic flame wars would often erupt. Eventually the arguments became so illogical and the insults so repetitive that often it needed to be pointed out that the OP was being a hypocrite.

NO U is originated back to simpler days when we as children would engage in what were to be the precursors to forum wars. Arguments over common issues would devolve into anarchy as neither party was willing to concede their point. This inevitably led to attacks on character which subsequently devolved into childish name calling which of course would usually finish with NO YOU. A major problem is that it can start an endless loop of NO U. These are known "No U Wars."

As long as there are forums where any asshat with an opinion can post, NO U will always have a home. Short of ignoring idiotic comments, this is a simple and effective way of pointing out that the OP’s comments are in fact more aptly applied to himself than his subject.

The ultimate trump on the Interwebz. Ends all arguments and debates.

Similar to the religious argument, "you have no faith."

The mother of all negative commands and the penultimate command of non-affirmation, which being one of the oldest words of the English language, dates all the way back to Old English. It is composed of simply two letters: The fourteenth letter of the alphabet, N, and the 15th, O. In this context, it is followed by an intentional misspelling for the word that describes a party that is a second-person subject to a direct address by another party, simplified with simply the 21st letter of the English alphabet, namely U. This intentional misspelling is used to express and emphasize the how much ignorance the speaker has in correct English spelling, which is common in the modern Internet world, and therefore, this misspelling is used as a subtle tool of assimilation into the complex society of the Internet. A blank space is traditionally added between the first two letters, N and O, and the last letter, U, most likely to add a non-casual taste to the originally very casual nature of the phrase, by not sounding like a nervous first-time public speaker rushing every single word and constantly putting two words together. Put together, and you have this phrase, the penultimate counter-attack to any hater trying to roast you hard, the remedy to any insult or unpleasant remark you may receive from your "friends".
