The "Kaka" part was obviously suggested to Chris by a non-benevolent source, but I'm amazed that he's that stupid to not put "kaka = shit" together. Yes, amazed, even after all the incredibly stupid things Chris has said and done before this.

I'm gonna go out on a limb and say that KaKa loosely has to do with his temporary fandom of Katy Perry. The "Kaka Makeup Basics" video has him playing California Gurls. My guess is that it's a cross between Katy Perry and Lady Gaga?
Essentially, Kaka being a Sonichu-like hybrid of the two pop stars, which manifests in Chris' tomgirl persona.
That's probably how the idea was sold to him, but he's still a tard not to say "That sounds to much like a word for poop".
