There was a thread like this a long while ago, but it's all good. I like Chocobo naming threads anyways.

Good/Great Male = Boco
Good/Great Female = Coco
Blue = BBKing or Keb'Mo
Green = M.Jane or Pot or Weed
Black = MNight or Knight
Wonder = Wonder or Super or Boco
Gold = Aurora or Richie

Of course Green Chocobos are my favorite!
