noob --- shorthand/leet spelling of "newbie". Also spelled 'n00b', with two zeroes rather than two O's (see leet) or 'newb'. In some internet circles, the term 'noob' or 'n00b' has a negative connotation, generally not assosciated with 'newb' or 'newbie', where being a n00b carries a connotation of ignorance and laziness. A n00b may be too lazy or stupid to RTFM or otherwise attempt to find out about a subject oneself, even if the information is within easy reach, and instead chooses to bother others. A newbie, on the other hand, is simply someone new to a subject, with no particularly negative connotation.
