An idiot. Specifically, one who is woefully naive and lacking in knowledge of a specific area of expertise (in a fandom, game, or online), but is so convinced that he/she knows far more about said area than most other people, that they blatantly disregard, and often fight against, helpful suggestions and opinions from other, more knowledgeable people. This is different from a newbie in that, while both are inexperienced and unknowledgeable, a newbie can learn as he/she gets more aquainted with the fandom/game/internet forum/group, whereas the n00b is so delusioned by their non-existent knowledge, that no ammount of convincing will deter him. The n00b refuses to admit he/she's naive in the area that they claim to have knowledge in and actually *learn*, and, instead, flames other people and generally act like a complete and total idiot trying to convince others of their imagined intellectual superiority. Generally the cause of flame wars.

Also can be referred to a person who excessively flames people, reviving dead topics, etc., just to get attention and/or make a point. Often gets banned from internet forums and causes many forum threads to be closed from further posts. Overall, a real jerk.
"That guy is such a n00b, still insisting he got the God of Assmasters playable in MKT..."

"Why do you keep on flaming me? The thread was long dead, and you had to bring it back from the dead just to take a stab at me? God, what a n00b..."

A n00b is a player or member of an online game or forum who acts in a generally arrogant and rude manner. The term n00b is often confused with the term newb, which refers to someone new to an online game or forum. While one must lack skill and competence to be a n00b, lack of skill alone is not enough to define one as a n00b. N00b is more of a reference to the attitude or demeanor of a player than to their skill. As a rule, n00bs speak in 1337speek and occasionally all caps. To be a n00b, one must first convince themselves beyond all doubt that they are the best at their chosen game, and like to prove it by killing level 1s. Noobs often ask for free gear or money on online games, and will insult the player in question when they are decline their said free gear or money. Similarly, when n00bs are offered advice as to how to become better at the game, they will usually ignore the advice and will often berate the one attempting to help. N00bs will often themselves use the word n00b to insult friendlier or more exprienced players. N00bs are notoriously bad sports, and upon being defeated n00bs will often call the player who beat them a H4X0R (hacker) or accuse them of being cheap. In the event that a n00b actually wins (usually after defeating a level 1), the n00b will announce their superiority to everyone in the vicinity. On forums, n00bs will often revive dead posts, ask to be a staff member in their first post and flame people for no reason. It is a common misconception among non-gamers and newbs that the only person that would ever call someone a n00b is someone who spends 15+ hours a day in front of a keyboard. These misconceptions usually stem from being called a n00b. In most cases, the one who called the newb or non-gamer a n00b is a n00b themselves. N00bs usually lack proper spelling and grammar. N00bs use excessive amounts of exclamation marks, and will occasionally use 1s in the place of said exclamation marks. The reasoning behind this is unknown. If a n00b somehow manages to team up with other players, he will blame the other players for all of his mistakes. N00bs will often demand to be the group leader. N00bs can usually be identified by their username.
A few examples of n00b behavior:

n00b: Fr33 g34r plz.
Level 70 player: No.
n00b: OMFG STFU n0000000000000b I h8 u f4G!!1!!1!!!!111.

A pretentious term used by people who honestly believe using numbers to write words is still as cool now, as it was when the running man was considered a great dance move. Used to half-assedly insult a person who annoys the user without the necessary thought that usually goes into such a response.
In other words you don't actually need to think of a response as long as you just throw "n00b" into a five crap lines that usually break the rules of a forum anyway.

More often than not the user is often far worse than those they use it on.
*boy that guy's lame...I'm totally gonna tell him off.
"N00b!!!!"
*yessss."
"That'll learn 'em to goof off on UltimateSpaceFragOmniMercsElite.com This place for serious discussions on "fragging zombies in space with half naked women..."
*....now where's my penis pump and a my sweet-assed pic of Samus Aran bending over to tie her space boot.....*

The term "n00b" is commonly confused with the term "newb".
A newb is short for a newbie, someone who is new to something.
A n00b is someone who, regardless of experience, is utterly crap at a game and will not take the advice of others.

These are generally big mouthed people who suffer from Delusions of Grandeur.

Upon being given advice, n00bs will either ignore it completely, or make a poor attempt at insulting the person giving them the advice.
A n00b will be the first person to point the finger at someone else if a mistake is made.
They are also the people that go around calling others n00bs for no particular reason.

90% of n00bs are unable to spell.

The word n00b is also commonly used in banter.
n00b: OMG, nyce shield lololol cn i buy plz?!?!?!?!?1
Player: Sorry, not for sale
n00b: OMG! n00b!

Person: Hey, can you plant the bomb please?
n00b: F U!!!!!!!

n00b: i r lyk 2 gd 4 u n00bs

*n00b charges one enemy and gets his ass handed to him*
n00b: wer th fk r u gys? i hd no bckup thr n i hd 2 fite 5 n00bs, bt thy killd me coz u ddnt hlp me. u r sht
