A colloquialism for the term "Bitches". Used in conjunction with the added "Z" vernacular, much like the added "nit" terms as well. See also "Shiznit" or "Hizoes".
A combination of words bitch and business. The word could be a sly way of calling someone a bitch while ostensibly telling them to mind their own business.
That fat cow from HR kept prodding me about my past employment records and if I had any convictions. Finally I had to tell her that it was none of her bizyatch! Needless to add, I am still seeking gainful employment.
