Haha, I legit had to dig to figure this out. See, the name comes from my second LiveJournal, which I got because I had pretty terrible memories associated with the first one. But after logging back into that account after literally years and going through the posts, it turns out ... there really isn't an explanation that I left on there. Like, back around 2006, I started asking for names, and that one just popped up on the lists I gave my followers back then with the note "don't ask."
So, literally, I can't remember. XD
