The noise required to mask the sound of anal secretion and subsequent bowl splash in a public or private restroom when one or more persons are in attendance with the person discharging, to thereby avoid the awkward silence that is present and periodically disturbed by the excretions of the person in question.
Dude, that was really awkward. The guy in there was playing his ipod, utilizing its brown noise capabilities.

The whole time I was in there this dude kept coughing to cover up his dump. He was clearly brown noise(ing).

Exaggerated chaos that ensues following a relatively small act or event. Refers to Episode 317 of South Park in which Cartman's mission to find the brown noise creates a domino effect that leads to devestation and destruction around the world

1. An unwanted, undesirable noise, similar to 'white noise' but commonly associated with people who TALK SHIT
2. A distracting noise which tends to cause confusion, disillusionment and temporary memory loss. Caused by simple, audacious imbeciles TALKING SHIT
