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.)

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....
