Haha, what an alarming statement!
I think that lady is either very naive, or likes attention. Imagine having to have that conversation almost everywhere you go! Having to explain the name like that. The fact that she tries to play it off with an eyeroll is interesting. You might as well own it! Make up a story about making a dark pact with a stranger at a crossroads at midnight or something, c'mon.
Anyway, I like the name
Lucifer. I actually quite like it for a girl too, because it's like
Lucy +
Jennifer =
Satan? I'm into that. Possibly best for a fictional girl. Or a hamster.
