The term Beotch or Biotch- where'd it come from?

Does anyone know the origin of this term? I searched for it here but found nothing. Other than for emphasis, I can’t come up with where this might have been coined.

The first I heard it was on Beavis and Butthead.

Snoop Dogg said it before B&B. Before Snoop Dogg…

I’ll get back to you, but I know that it was a part of the gangsta-rap lexicon before Mike Judge injected it into the vernacular of our favorite Highland High students.

South Park also featured it, but that probably postdates B&B.
