The sound of brown. It is a low pitch sound that makes the listeners asshole go "BLAH!!," leaving the pants of the victim heavy and very very brown.
When I was at that rap concert last night they hit the brown noise and all the niggas in the house shit demselves.

An oscillation of sound that causes the bowels to loosen. The brown noise is believed to be ninety-two cent below the lowest octave of E flat.

The brown noise was discovered by the french, and tested as a weapon during WWII. It is a a 12 - 14 Hz sound wave that, when played loud enouch, relaxes your sphincter, causing loss of bowl control.

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.''

Unlike the "Brown Note", The Brown noise is the sound that comes from a female as a penis is inserted into her anus with no warning, the sound can very from ooooo, to ahhh!, to "what the fuck are you doing!?! oww!!!" (this maneuver can also be preformed to a streaking male that has been spotted by a randy homosexual.)
"That bitch made me watch The OC and fucking cuddle... so that night I heard the brown noise... it was swearing followed by hysteric crying."
