A note that is ninety-two octaves below B-flat. Hearing the brown noise makes people have an uncontrolable urge to shit their pants. The brown noise was once used in a episode of South Park.
''Hey man, did you hear about the musician who accidentally played the brown noise? Yeah, the entire audience shit their pants.''

Noise showing a random walk behavior, as in Brownian motion. It has a 1/f^2 frequency spectrum. It has nothing to do with crapping your pants. Try learning some physics....
You guys are retarded for thinking a brown noise can make you crap your pants.

An oscillation of sound that causes the bowels to loosen. The Brown Noise is believed to be 92 cents below the lowest octave of E flat.
"We're trying to find the Brown Noise. It's this one pitch, this certain frequency, that makes people lose bowel control!"

Communication that's usually complete bullshit or just painfully annoying.
He open's his mouth and all that comes out of it is brown noise.

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).

A certian musical note that when heard makes you shit yourself. Also when in large groups the result can be severely devastating.
*Brown noise*, Oh SHIT!, I crapped my pants!
