/filk/ [SF fandom, where a typo for "folk" was adopted as a new word] A popular or folk song with lyrics revised or completely new lyrics, intended for humorous effect when read, and/or to be sung late at night at SF conventions. There is a flourishing subgenre of these called "computer filks", written by hackers and often containing rather sophisticated technical humour. See double bucky for an example. Compare grilf, hing and newsfroup.
