Someone who loves maps excessively; they have tons of them in their home.
I'm a Bigtime map fanatic & have so very many maps in my house & love them all. Maps of the Constellations, globe, world maps, atlases, state maps, local maps.
When a person on Facebook becomes fans of literally every little thing they believe that they are associated with. The person shows how hip they are by being fans of everything cool and appearing to be interested in things for attention.
Friend 1: Jeez, Joe is now a fan of getting crunk, sleeping in, the NFL, and like 10 other things.
Friend 2: Wow, Joe has really turned into a facebook fanatic hasn't he?
