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."
