fattest inspired me to put a little note explaining the origin of my LJ nickname in my bio, in case you're curious. There's more of a backstory than I provided in that particular spot; basically, Nadine is the most overlooked of my three cats, so I use her nickname to make up for it. Also, purely from a practical standpoint, "Nadinelet" is blessedly unique when it comes to making up Internet handles.
Just remember, it's the cat's nickname, not mine.
