From the latin root
words "dundus" "rundus" - most accurately, the act of stealing another's basketball and booting it as far as possible therein bringing the game, or "run" to an unwelcomed end. This act of booting is usually accompanied
by a spirited chant of the words "DUNDARUNS!" Dundarunning
usually is done to communicate a message of superiority or general
or "foul pitany". The term
has evolved in colloquial use to a more general
application outside the realm of "ball-booting" to signify the conclusion or finality of an event - e.g. "the movie is dundaruns".
