A few years back my friend went through a Japanese nicknames phase. Since my name's Kitty she branded me as 'Neko-chan' (neko being cat in Japanese, the -chan implying it's a kitten although koneko would have been more appropriate). I'm also incredibly pale and often get told I look deathly ill, so I combined necro (dead or of the dead) with oid (to be similar to or of such properties) and viola!
So long story short, I'm a dead-looking cat.
