"Noob" is a simple insult, and so only requires a simple explanation.

Everyone wants to believe that they are good at the things in which they've invested a considerable amount of time. Calling someone a "noob" insults this belief, and so tends to cause a lot more of an emotional reaction that it otherwise should.

Just keep in mind, every game through the matchmaking system attempts to match you against people who are roughly as good as you are at the game. This means you have basically no reason to insult the people you're playing with -- they're about as good at the game as you are.
