NIMBY (an acronym for the phrase "Not In My Back Yard"), or Nimby (as a word, instead of an acronym), is a pejorative characterization of opposition by residents to a proposal for a new development because it is close to them (or, in some cases, because the development involves controversial or potentially dangerous technology) often with the connotation that such residents believe that the developments are needed in society but should be further away. The residents are often called Nimbys and their state of mind is called Nimbyism.
