The Khia of "Pay Yo Pussy Bill" is Khia as Khia is intended to sound. She very skillfully vacillates between a range of tones; she nasally, then guttural, then grainy, then nasally again, then delicate. (And yes, that's how she's supposed to do it.) She's sultry. She's goofy. She's sounds slightly absurd. She's fully engaged. She's expressive in ways that "technically superior" vocalists just aren't. She is brilliant. You have no idea how brilliant she is.
Having seen Patrick's posts several times on this site, I'd say there's a pretty good chance that post of his was supposed to be tongue-in-cheek. That people took it seriously and cosigned it with complete sincerity is far more embarrassing than the post itself.
