not in my back yard

Not in my back yard, which is often said in its abbreviated form, NIMBY, is someone who opposes anything built where they live or in the same area. This is often used for neighborhoods where large corporations choose to put new businesses, parks, shopping malls or other types of places within their neighborhood. A NIMBY, or Not in my backyard type of person, opposes all of this because it ruins their idea of a good neighborhood.
