newbie, newb, noob, nub, or n00b is a slang term for a novice or newcomer, or somebody inexperienced in a profession or activity. contemporary use can particularly refer to a beginner or new user of computers, often concerning internet activity, such as online gaming or linux use. depending on the context and spelling variant used, the term can have derogatory connotations (and be used as a term of abuse in internet-based games)—but is also often used for descriptive purposes only, without any value judgment.
the origin of this term is uncertain. earliest uses probably date to late twentieth century united states armed forces jargon, though possible precursor terms are much earlier. variant forms of the noun include newby and newbee, while the related term noob (often stylized as "n00b") is often used in online gaming.
