/filk/ [from SF fandom, where a typo for `folk' was
adopted as a new word] n.,v. A `filk' is 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 humor. See double bucky
for an example. Compare
