StealthCoin
If you need that one, I think I know who owns it, because as far as I remember I suggested it to him in April 2013.
My humorous ideas are:
007gold
anarchoin
autonomoney
cashown
coinpute
coinwetrust
ellodium
fu8all
fucash
goverup
kingkoing
koindly
rallodial
telegold
I own autonomoney and it is available for any reasonable offer.
