A rhetorical question, this phrase can be used in conversation about someone who has been sexually promiscuous. The phrase refers to the noise made by the female genitals and anus slapping together, after being stretched out of proportion by one or many sexual encounters.
Example - "Whats that noise? Oh yeah I forgot, its your bucket fanny slapping against your bucket anus!"
