nawb is another word for noob, or any other form of that word. Word thought up by Leedle and Methmaster from RuneScape. In making fun of their clan leader, Jibs2ndpure, they called him Jawbs and made noob rhyme with it. Then they started saying nawb and started calling him "Jawbs2ndnawb" and stuff like that.
Haha, look at that nawb, he is almost as nawb as jawbs.
