newbie

newbie /n[y]oo'bee/ n.  [orig. from British public-school
   and military slang variant of `new boy'] A Usenet neophyte.  This
   term surfaced in the {newsgroup} talk.bizarre but is now in
   wide use.  Criteria for being considered a newbie vary wildly; a
   person can be called a newbie in one newsgroup while remaining a
   respected regular in another.  The label `newbie' is sometimes
   applied as a serious insult to a person who has been around Usenet
   for a long time but who carefully hides all evidence of having a
   clue.  See {B1FF}.
