Oh? Like in my user name? Well, mainly it's because I like foxes. "Fluffy Fox" just sounded good together and then "Of Fate" was due to me playing a lot of Fire Emblem Fates at the time I made it. Then It just stuck and it's been my user name online in a lot of places. ^^ (then later I drew my own sona, my profile picture, that's also a gray fox/cat so it works out with that too.)
Hope that answers you're question.
