n00b

An idiot. Specifically, one who is woefully naive and lacking in knowledge of a specific area of expertise (in a fandom, game, or online), but is so convinced that he/she knows far more about said area than most other people, that they blatantly disregard, and often fight against, helpful suggestions and opinions from other, more knowledgeable people. This is different from a newbie in that, while both are inexperienced and unknowledgeable, a newbie can learn as he/she gets more aquainted with the fandom/game/internet forum/group, whereas the n00b is so delusioned by their non-existent knowledge, that no ammount of convincing will deter him. The n00b refuses to admit he/she's naive in the area that they claim to have knowledge in and actually *learn*, and, instead, flames other people and generally act like a complete and total idiot trying to convince others of their imagined intellectual superiority. Generally the cause of flame wars. Also can be referred to a person who excessively flames people, reviving dead topics, etc., just to get attention and/or make a point. Often gets banned from internet forums and causes many forum threads to be closed from further posts. Overall, a real jerk.
