Fuhgettaboutit is a word that most Italian-Americans (usually from New York or Boston) use to say "forget about it" or "don't mention it". I as an Italian-American find myself slipping up and saying instead of "Forget about it, that's all right!" I say "Fuhgettaboutit, that's all right"! This can be used by people other than Italian-Americans, but it originated from our roots.
