The online Urban Dictionary defines Fandemonium as
But let's face it: before the early Star Trek and Comic Con conventions of the 1970s,
there were plenty of other excellent reasons to be a part of a mob scene and scream your lungs out.
Really good reasons!
and the Rolling Stones
(just to name a few).
I am proud to have played my part as a screaming teenager back in the 70s at Rolling Stone concerts
(and would have loved to have joined in during the 60s, but I was too young).
Take it from me (an ex-Mick Jagger impersonator) that for some of us,
Fandemonium encompasses so much more of our daily lives than attending crowded conventions.
So I like to apply an "expanded" definition to the word.
For me, Fandemonium is to love "something-or-someone" so much
that the constant need for "it-or-them" to be a part of your life
is so great that you alter your lifestyle to incorporate "it-or-them"
into your daily routine (or even persona) in some form or another.
To truly experience Fandemonium is to wear many hats,
because true Fandemonium consists of a minimum of the following activities:
Digging up as much information as possible on the thing-or-person you love;
(the Researcher & Historian hats)
Collecting photos, articles, assorted paraphernalia, and possibly locks of hair regarding the thing-or-person you love;
(the Curator & Collector hats)
Constantly extolling the virtues of the thing-or-person you love to others whether they are listening or not.
(the Cheerleader & Free PR Agent hats)
