how did you get your name “nixie”?

My friend was writing some stories and stuff and I thought she came up with really good names and such so I asked her how she came up with them and she told me she used a ‘fantasy name generator’ so I decided to look at it one day for fun and got Nixie out of it and idk I just used it ever since that literally, at this point it’s weird for me to type out my actual name sometimes. I think I have been going by ‘Nixie’ for about a few years now.
