Unwanted, incomprehensible , high volume, noise that is produced by a group of black people all talking at once.
Person 1: My black friends and I went to see a movie last night.
Person 2: That's cool. How was it?
Person 1: We had fun but, I couldn't even hear the movie because of all the blackground noise they made.
