    katsu

    This is Chinese character he,
    which is the "shout" given by
    Zen masters and their students.  
    Katsu, or kwatz, are the
    Japanese pronunciations usually
    given, though not really accurate.

    He is a grunt sound from the
    hara, that many martial artists
    use when they throw a punch.
