'Azz Everywhere' (Instrumental) by Big Freedia is performed in a style of rap. It does not carry any meaning at all, the essence of the whole 'Song', if it can be called that, is reduced to the repetition of two or three words and shaking booty in the clip. Something very third-rate, junk, in fact. It's not even a song at all, but simply a circling of the same words with a cacophony of sounds.
