A sound effect from early 90s video game, Super Mario World. This particular sound is made when the character, Yoshi regurgitates an enemy out its mouth resulting in a noise resembling the word 'bow.' Can be used in response to just about
anything said to you. Occasionally this word has a rippling effect and once triggered by one
person can result in a room full of
people repeating the word over and over until everyone is in a state of hysteria.
