Mundane vs. Insipid — What's the Difference?

In subcultural and fictional uses, a mundane is a person who does not belong to a particular group, according to the members of that group; the implication is that such persons, lacking imagination, are concerned solely with the mundane: the quotidian and ordinary. The term first came into use in science fiction fandom to refer, sometimes deprecatingly, to non-fans; this use of the term antedates 1955.
