In Celadon Boomer calls me Dr. L and Cousteau calls me "yougin", from Lionel and Lobo. e.e Lobo calls me "sweetie" now, so now I have a little frog claiming he's older than me.
Kiki calls me "muffin", which I find to be the cutest thing ever. <3
Both of my peppies suggested the name "pop star"; I accepted it the first time, but then another asked to give me exactly the same nickname, so I declined.
Some call me "fluffy", some call me "Dr. F", some call me "Lil' K" (on my mayor), at this point I forgot what else I'm called. If there were enough characters, I'd want to put in my Pokemon nickname, "Fishnugget".
