1. The sound Donkey Kong makes upon doing his taunt in super smash brothers. Usually accompanied by a shrug of the shoulders and a rocking back and forth of the head

2. An imitation of the above done to other people, usually to provoke anger as you are kicking their ass with Donkey Kong in Super Smash Brothers.

3. Au-oooooo!?
Person 1: Oh my god you're kicking my ass with Donkey Kong and there is nothing I can do about it!

Person 2: *motions like DK's Taunt* Au-OOOOOO!?

Person 3: Oh go fuck yourself.
