[Usenet] A notional repository of all the most dramatically and abysmally stupid utterances ever. An entire subgenre of sig blocks consists of the header “From the fool file:” followed by some quote the poster wishes to represent as an immortal gem of dimwittery; for this usage to be really effective, the quote has to be so obviously wrong as to be laughable. More than one Usenetter has achieved an unwanted notoriety by being quoted in this way.
