Sasha actually talks nasty to "Nasty". Great turn of phrase!!

No one taught Sasha this behavior. It is part of her genius. An essential on her road to fulfillment.
It is her expression of "Being and Nothingness" where she projects her anguish and despair in the form of explicit and degrading dialogue, states the inconsequentiality of "choice" itself by not opting for any single dick or hole to put it in, accepts the burden of all mankind by eagerly taking every load in her mouth and, finally, the zero net sum and inescapable end of our existence by swallowing billions of potential human lives ...
Either that or she's fucking SICK!
