Forum N00b
A n00b is leetspeek for "noob" that comes from the word "newbie" or "newcomer".
The n00b is a newbie, but unlike the Normie, fails the test of Forum Introduction, possibly due to low quality posts, bad English, boasting, being a Forum Arsonist, bumping threads, not listening to advice, creating pointless threads, creating tournaments when you are very new to the forum, lacking common sense/social skills, or really horrible bot building skill or any mixture of these. Basically just being annoying/obnoxious without contributing anything interesting. Also often a Forum Arsonist, Vet Whacker or Drama Queen, though not all forum arsonists/drama queens are noobs.
A person can stay a n00b for a very long time (sometimes called perman00bs), or can hopefully evolve into a Normie.
Contrarly to newb, n00b is an offensive term/insult.
It is told that you can kill n00bs most effectively through flaming. Well known n00bs are Sparkey98,LRA2 and GarvinTheGreat. Often the target of n00b whacking.
