Someone who is bad at a
videogame. Typically noob (pronounced new with a B at the end) will be a player who has owned and played the game for awhile now but due to their ignorance, annoyance, over
confidence & general stupidity, they will suck at the game.
These people usually will throw the word noob out which is also a classic example of the more you use it, the more you probably are it. General examples of a noob's behavior are players who betray/team
kill their team mates for taking a weapon or vehicle they wanted. Players who have a game virtually won, but continue to play or spawn kill the other team because they're either bored or find it funny.
As you might have guessed - noobs usually don't have much of a life and take their
depression out in the
videogame world... The one place they can be better then somebody. Noobs also find it necessary to talk shit to the opposite team whether they win or lose.
Please don't confuse Noob with Newbie. The latter means the player is simply new to the game & not necessary a idiot of life.
