A noob is a derogetory term derived from the word Newbie (a newcomer to a particular field). The term noob is used on the Internet, where it might refer to ignorant users of a game, a newsgroup, an operating system or the Internet itself. (Note: Newb is different from noob. Newb refers to new player while noob is described above)
As explained above, noob is mainly used to insult players that don't behave as experienced players do. Frequently the terms "noob" and "newb"/"newbie" are used interchangably, but many Tibia players insist that they are fundamentally different (see below, and the article Newbie for comparison and contrast).
The use of the term noob is sometimes but not always related to being new to Tibia(see "newb" below), the label is often put on those who act foolishly or otherwise exhibit behavior that is childish and/or irritating to other players (even if they are experienced players themselves)
The use of the word noob is common near town Depots and the center of Rookgaard, where the noobs hang most of the time. They often ask other players (usually high level players) for items. They move people that stay outside Depots (outside Protection Zones), spam the default channel, and from time to time attack players.
Noob can also be written as nub or nab and as n00b in leetspeak. Also "upside down" - qoou, qeu and qnu.
People who stand in the doorway of a depot are sometimes considered noobs.
Also people who kill dogs are also considered noobs. (Except in Thais where it seems to be popular.)
Many people often mimic the behaviors of noobs in order to irritate higher levels and/or those who take the game a little too seriously (see "losers")
Sometimes it is necessary for one to act in a noobish manner in order to expose the utter foolishness of the usually higher level character, coequally referred to as "[a]loser" or "person who plays to much Tibia"
When noobish behavior is used to counteract the behaviors or attitudes of the aforementioned "losers" it is deemed a worthy action.
Ironically, the word "noob" is used most by the people who in fact are noobs.
Character named Noob existed and was banished permanently because of invalid payment.
