Wordnik.com’s “Word of the Day” for May 25 is “filk” —
adj. (adj) About or inspired by science fiction, fantasy, horror, science, and/or subjects of interest to fans of speculative fiction; frequently, being a song whose lyrics have been altered to refer to science fiction; parodying.
The Wordnik post takes its definition from the Wikitionary entry for “filk”.
Unlike most developments in the history of popular culture, how the word “filk” got its start is precisely known. Lee Jacobs typoed the word “folk” in the title of his manuscript “The Influence of Science Fiction on Modern American Filk Music” intended for distribution in a mailing of the Spectator Amateur Press Society in the early 1950s. While I’ve never seen the article and can’t say what the problem was, Wrai Ballard, SAPS’ official editor at the time, feared its bawdy content could get him into trouble with the Post Office under the Comstock Laws and he refused to send it out. Ballard nevertheless enjoyed the typo, as did the others he told about it. “Filk music” rapidly became part of the faannish jargon.
Thanks to Lee Gold, we even know that the first composition to designate itself a filksong was “Barbarous Allen”, lyrics attributed to Poul Anderson, in Karen Kruse Anderson’s SAPSzine Die Zeitschrift für Vollstandigen Unsinn #774 (1953).
