XXX

Origin

1969 (see quotations). Reduplication of X (“an age rating denoting content suitable for adults”), in reference to the X rating introduced by the Motion Picture Association of America on 1 November 1968 for films containing extreme violence, heavily implied (originally softcore) sex and obscene language. Film posters began to include multiple exes (but skipping two) in order to imply even more extreme, hardcore content, particularly in relation to pornography (although many actually contained the same content as X-rated films). Compare XXXX. The original X rating was superseded by NC-17 in 1990; see also R-18.
