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.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.

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.

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.)

it is an e-flat note from the recorder that allows the bowels to loosen (in other words crap your pants)
it was used in world war 2

Ok the brown noise ,basicly, is so low...you crap your pants
