what is a fanlisting?

Statement: A "fanlisting" is a strange meatbag custom in which many other meatbags add their name to a list, thus professing their admiration for a subject.

Admission: I seem to have many meatbag fans. I must profess a certain confusion by this custom, despite the fact that it provides one with a handy list of potential targets - er - friendly meatbags.

Clarification: I am given to understand that more information about these "fanlistings" can be discovered in The Fanlistings databases.
