Noob 

Noob: a beginner, ignorant git, bastard, idiot. Although once used as an insult, nowadays it is commonly thrown out in chat for no apparent reason.
Noobs are no to collect in 'tribes'; and unorganized group of noobs who chat, horse around, and generally cause minor chaos. Often use 'Noobish Language' which consists if numbers in the place of letters, improper grammar, and vulgar slang. Often noobs accuse fellow noobs of being noobs, which start 'Noob Scuffles' in which the noobs argue over who is better at no scoping, who is noobier and who has more 'skillz'. You'll find large concentration of them in Hack Forums, Minecraftcraf, Halo, and other shooting games.
Often referred to as n00bs, newbies, newbs, and stupid.
*EXAMPLE OF NOOB SPEAK:

noob 

an absolute retard who spends most or all of his time on a netgame or forum, acting dumb and irrational.
Occasionally confused with "newb" which is a person who is new to a game, a noob/n00b/nub/nubz0r may be very familiar with said game, but because of his total lack of an IQ still suckx and refuses to admit so.
Noobs may also continuously spam or annoy people with their idiotic nerdspeak "1337 or n00bish" thus leading them to be banned, squelched, or ignored entirely.
Many noobs also lack friends, people who care about them, the ability to speak normally, and a life in general.

noob: LAWLAWLAWLAWL I PWN JOO!!!!!1!!!1111ONE!!
person: do everyone a favour and stop breathing

(look up elementalkirby on youtube, primary example of noob)
