General English

  • adjective relating to the mind


  • adjective mentally ill, subnormal or deranged, crazy. A widespread colloquialism which showed signs of losing popularity in the 1970s, perhaps due to increased sensitivity; this tendency was reversed by punks, fans of heavy metal and others who enthusiastically adopted the term to refer to their characteristic frenzies, headbanging, etc. In these circles the word may be used to express admiration.
