look up any word, like fleek:
 
1.
Booty-(n) and Belch-(v): booty belch - is another way of saying that an individual has farted and/or passed gas.

This occurs when the anus produces a sound that would normally be associated when an individual releases gas orally and/or belches, but it is produced by the anus.
When the sound came tearing from her behind rather than her mouth i couldn't make sense of it. Then I realized it was a phenomenon known as a booty belch!
