"Fnord" () is a word coined in 1965 by Kerry Thornley and Greg Hill in the Discordian religious text "Principia Discordia". It entered the popular culture after appearing in "The Illuminatus! Trilogy" (1975) of satirical and parody conspiracy fiction novels by Robert Shea and Robert Anton Wilson. In these novels, the interjection "fnord" is given hypnotic power over the unenlightened, and children in grade school are taught to be unable to see the word consciously. For the rest of their lives, every appearance of the word subconsciously generates a feeling of unease and confusion, preventing rational consideration of the text in which it appears.
