N00b, noob, newb, newfag, or any other variation of the word is a derogatory term for a person who is new to something. In the context of this Wiki and online community, it refers to a new spriter who acts stupid or a spriter that's been around a while that just acts really stupid. Only the ruder spriters, or 'noobs' in denial will use this term against somebody.

If you want to be polite, call a new spriter a "new person" instead of a "n00b" or "newfag."
