Based on the Brazilian and AC Milan soccer star Kaka.
His actual name is Ricardo, but Kaka is his popular nickname, and he's actually respected.
I wondered how any dude could pull off a name like that. I do believe kaka, caca, is one human universal meaning for human...eh...depository material.
Then just on hearsay, I found the website Kakafans.net
They'd have to be really fuckin' dope to pull of a name and change it's association from something crappy, literally to something that people actually want to be fans of.
Kaka! Para la victoria!
