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.
