Nicknames are funny things. "Scott" doesn't lend it self to many nicknames, except the obvious Star Trek references. (My Dad used to call me "Scooter McGruder.")
"I'm givin' her all she's got, Cap'n...", "Beam me up.", etc.
I'm a huge fan of all things Science Fiction, so the rest of the Band just started calling me "SciFi." I like it. Since, generally, one does not choose their own nickname, I feel fortunate to have been given one that I have no problem with.
It's kinda nice having separate identities with the different acts...
