filk /filk/ n.,v.
[from 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 and/or music, 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 grilf, hing, pr0n, and
newsfroup.
