I tried to fit the Dunesfolk Lalafell naming convention of AAB - CCB, with the two B's rhyming with each other.

"Kokoro" = Japanese word for "heart".

"Liliro" is made up but the "Lil" part should probably conjure an idea of being little or small.

So "Heart Little" or "Little Heart".

As for my forum name of "Moofia Boss Val", I played forum mafia on a WoW fansite. I was called "Val" back then. I had my Tauren paladin in my signature. During one mafia game, a poster joked that I was "the Moofia boss" (a play on the Mafia boss, who is the leader of the evil team of players in mafia games), so I named changed my username to "Val the Moofia Boss".
