1. Someone who is in-experienced at something

2. A word overused by geeks with delusions of superiority who think they are cool because they have no life and play computer games 24/7. It is often, for no apparent reason, spelled with zeros instead of O's, another geek thing, e.g. n00b instead of noob.
"Ha ha ha, that kid has a life and isn't a grand master at this game like me, what a n00b!"

A n00b is someone who has no internet edicit whatsoever and yet still persists to use the internet almost all the time annoying the living shit out of anyone he or she or it meets.
How to act like a n00b.
1. Stop caring what anyone thinks or you.
2. Learn to love being annoying.
3. Learn every single racist, sexist, homophobic, and sacreligous term known to man and use almost everysingle one of them everytime you talk to anyone.
4. Lastly and most important of all, Stop having a life and spend all day on the computer annoying everyone you can find.

N00bs are most often found online, where anonymity tends to cause people to believe that they can say or do anything without consequence. Example: A 9 year old would never go up to a group of older teenagers and yell “You are gay, you stupid fags!” but online this happens all the time. (Although it would usually look like “U R gay u stpid fagz!!1/”)
N00bs can be found in real life as well, but this is much less common.
In general n00bs are usually rude and ignorant. N00bs also tend to be unskilled at most online activities; incorrect spelling is the first giveaway.
Newbies are not to be confused with n00bs. Newbies are just new at whatever they are doing (New + baby = newbie) so they tend to be confused or unskilled, but NOT ignorant and annoying like n00bs.
Newbie “Oh man, I just got killed again… you guys too hardcore for me”
N00b “OMG! Stop kiling me u haxzors!!”

A term used in online discourse to belittle and bully others. Often an expression of impatience with a game-player who might seem less than proficient, but also just a handy insult for those without the vocabulary, manners, humour, tolerance or spelling that their mums hoped they'd have by that age.
A: Oh, bother. We lost the game, possibly because of an error on the part of player B. My life extends not much further than the online game world, so obviously I'm miffed. How shall I express my frustration? With a cheerful and sporting, "We'll get 'em next time" or "Don't feel too bad"? Nah! Hey, player B: "n00b!" That told him.

A retarded arrogant alcoholic fucktard who doesn't realize he is actually pressing a zero instead of an o. They are potentially dangerous, they might "pwn" or "rape" you while you are playing video games or on online forums. For safety precautions please wear a cup on your asshole when you play halo.
Nerd "zomg 1 pwn u n00b"
Hobbyist *puts cup over asshole*

someone who thinks they are better than other player/ causes needless arguments. also is a high level/ rank, but is completely crap at whatever they do.
Two real life incidents:

n00b: hey you english fag! big ben big ben! english teabag! you jealous of america!
english guy: shut the fuck up.

EX 2:
n00b gets a kill. starts teabagging body. killed player goes to spot of death, sees n00b still teabagging body. n00b dies explosively from behind.
