Newbie
Noobs are usually referred to by the 1337 (pronounced "leet") or skilled players, who have marginally higher experience in the game.  When a leet soundly defeats a noob, he is said to be "pawning noobs". Recently "noob" is used mainly just as a name to refer to other players in various online games.  It's usually a derogatory term, but can be exchanged as a friendly greeting. A noob is sometimes confused with a "choob" (a low skilled person in a game, but having acquired nice things as a result of playing).
