A mature granny who gives head to a pornstar is called a pornsthis refers to the act of giving head or fellatio to a pornstar. Black ho comes from the color black and there are many instances of porn stars receiving fellatio from black men. So what I'm saying is that a pornstar will get a black man to stick his penis in her mouth and that is how the term black ho came about. This is one of the reasons why I love my black man; he brings it on!.
