Cast Member Tributes

I found out today that some fans have come up with nicknames for the individual cast members who play Alice and the Mad Hatter.  It sort of goes against the official "there's only one Mickey" rule, but I like the idea of paying tribute to hardworking and creative cast members.  I suppose this all started with Maynard?

Of the Alices with nicknames, Gingersnap, Malibu, and Demure seem to have the greatest online presence.  A Google search of each of them (in quotes) finds results in the thousands, including videos, fan art, and even Facebook pages for two of them.

• Gingersnap Alice on Facebook
• Malibu Alice on Facebook
• "Rowdy" Hatter has one, too

Quite a lot of cast member fan art here:

Does anyone happen to know how or where this started, or if it's also a "thing" in Disney World?
