A reference to the Twilight Zone episode, "It's a Good Life," in which a mutant with
godlike mental powers, in the guise of a monstrous 6-year-old
boy, sends with
a wish anyone and anything that displeases him to a limbo-like void
known as The Cornfield. This term
is frequently used on Metafilter to describe the banishment, temporary or permanent, of members who disregard
of The Community.
Example: "Since I'm probably off to the cornfield anyway, Mano, fuck you. If you don't like it, don't read it."
