A Macro Furry is simply a giant furry (meaning a 50' fox, not
a 50' person who uses this newsgroup. To the best of our knowledge the
latter does not exist.) A Macrophile is someone who enjoys fantasising
about relationships with Macro Furries. Furry Macrophilia is basically
the furry equivalent of the Giantess
phenomenon in the 'mundane
realm, except that Macro Furries tend not to be so exclusively female,
nor so exclusively sexual.
Macro Furry artwork encompasses everything from harmless,
funny, G-rated work, to scenes of mass carnage and overt sexuality. At
the mass-destruction end of the spectrum, the archetypal Macro Furry
is probably Godzilla.
