It reminds me of Uffy, who is worse, and Tila 'Tequila' Nguyen, who was also shit. Shit rapping is shit rapping. Good rapping by posh girls would probably be shit, but it's unlikely a posh girl would ever be good.
I wouldn't say the Millionaires were the worst thing ever though. I'd have to not want to have sex with them for them to qualify for that.
