Do NOT, DO NOT confuse this with newb, someone that is new. Sometimes noobs can be newbs, sometimes someone can be a newb but not a noob and extreme cases a noob can be some1 that is not a newb.

The Master Noob is an almost otherworldly creature who creepishly influences all noobs. He is the only noob who can actually bring order to any noob pr noob infestation. If, say, a large amount of noobs overran a forum, the Master Noob could, with a small order, make all noobs leave forever! Although, there is a few catches. The Master Noob is the only one of its kind, meaning there can be no other. He does get lonely because he will only ever be able to a noob, not even able to advance to a newb. Though, most of the time he can handle this.

His anatomy is that of a human, slightly large around the edges, and tall. He comes once a generation, and this time he has taken form as me, an Australian.

The Riot Shield Noob. A player in Call of Duty:Modern Warfare 2 that uses the Riot Shield to get a quick laugh in multiplayer. Usually equipped with the Tactical Insertion and Commando Perk to get quick kills. Most likely camps in small areas where snipers like to hide. Luckily, easily killed by your daily Noob Tube or someone smart enough to go behind them.

The MW2 Javelin Noob. A noob that takes out the javelin in the begining of the game and randomly locks on to a target, usually getting 3 kills due to the facts that the other team moves together.
