Biznotch originally developed as a black way to ghetto-ize and change the traditionally white word "bitch." As time went on,
white people started using biznotch as well, and thus blacks stopped using biznotch and left it to be a white word. Today biznotch is the white equivilent of bitch, as the insult.
*Biznotch may not be used as
the definition of bitch - a
female dog.
