Whats with the Kate (B) jargon?

[hasn@midway.uchicago.edu]

I've been listening to and playing Ms Bush's music for
sometime now (my wife's a suprano and a pianist and
I'm a guitarist so it works out well!).  I also transcribe
Kate Bush's music (for personal use ofcourse).  So 
all in all I consider myself and my wife to be "fans" of
Ms Bush.  However one thing that has been bothering
me for a while is this Kate Bush jargon.  What's with
the Kateness, Katemas, Kateicle, and so on and on.
It reminds me of the sci-fi conventionheads or the 
Star Trekis (I saw them both in Chicago heading towards
their relative conventions).  It also reminds me of 
the episode of Saturday Night Live in which 
William Shatner played himself giving a speech 
at a Star Trek convention.  He said "Get a Life,
people, its not real, its a show, for god sake."  I'm
not implying that Kate Bush fans get a life, BTW.
I'm just saying that is it necessary to bring the 
( IMO, rather tackyish) Kate Bush jargon into it?
This is an honest inquiry, since I absolutely cannot
visualise of Kate Bush being the be-all-and-end-all
(however she is a great songwriter/performer/singer)
I do understand the nature of fan clubs, but why 
this jargoning deal?
