Noob

'''"Not to be mistaken with a Newb." '''

A Noob is a slang term for a newcomer to online gaming or an Internet activity. It can also be used for any other activity in whose context a somewhat clueless newcomer could exist. It can have derogatory connotations, but is also often used for descriptive purposes only, without a value judgment.

History
The word newbie is a variant of new boy or new blood and comes from British public school and military slang. Before it entered popular discourse by way of the Internet, the term "newbie" was used among U.S. troops in the Vietnam War as a slang term for a new man in a unit or squad. Online, the earliest reports of the word Noob being used came from the USENET newsgroup talk.bizarre circa 1981.
