   filk
      /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.
