The origin of this meme is a quote from Peter Jackson's 2001 film 'The Lord Of The Rings: The Fellowship Of The Ring.' In the scene, Boromir tells the Council of Elrond: 'One does not simply walk into ______.'

The term meme was introduced in 1976 by British evolutionary biologist Richard Dawkins (author of "The God Delusion"). He conceived of memes as the cultural parallel to biological genes and considered them as being in control of their own reproduction.
