(interj.) A portmanteau of "
wow" and "cowabunga". Used to express
one's reaction to
something that is both surprising and awesome.
David Bowman - "Oh my god, it's full of stars."
HAL - "Wowabunga homie!"
World of Warcraft junkie - "I gave up
WoW because it was ruining
my life..."
Rest of the
world - "Wowabunga!!"
