Most of the time, I pick up "Kiminality" for Forums or IRC, or such.
Failing that, there's the alternatives of "Deadly Brain" or "Scary Mojya"
Very rarely do I use Kiminality as a character name.
Generally, I think "In the unlikely event that I end up with a human worm-baby of my own, would I name it 'xxx'"
Obviously, that failed when I thought it would be a good idea to call a character "Angelic Panda" :/
