The noise the worlds most beautiful creature, Waluigi, makes.

Taken in the contest of the song Baby's Got Back by Sir-Mix-Alot he is referring to Florence Griffith Joyner a track athlete in the 1988 Olympics who defiantly fits all the other descriptions of what he likes in women mentioned in that song. Not some soda why on earth would you want to keep your women like a soda anyway?

Used by a Godly entity knowns as 'Waluigi'. This omnipotent being is the origin of the noise. He radiates such a divine presence that no human can go near him. Only through the word of 'WAH' can a form like his be attained. There is only one living human 'Waluigi' his name is 𝐀𝐁𝐈𝐍.

WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

Something our god Waluigi would say. He wants to be in smash.

The only thing the character "Waluigi" says in any Super Mario game

A subtle cry from a small human. Can often result from bad news or disappointment
