To quote the man who named me:
"I came up with it. I started calling her 'the sxKitten' on my hiply ironic blog, because I'm an ironically hip and hiply ironic sort of guy. She's not the sort of person that one would normally call a sex kitten: it refers, instead, to that late 80's phenomenon of attaching the letters SX to anything that some marketdroid wanted to convince you was cool. Like the 386SX. Remember those? She's also not terribly kittenish unless you get to know her really well (if you know what I mean), and that ain't going to happen."
