An obsolete term that doesn't really reflect today's usage of the similar faan.

from Fancyclopedia 2 ca. 1959
(Tucker) Bob's sardonic distortion of our title is pronounced with what is almost a bray, suitable for designating a group full of LMJ's and sheeplike followers.

from Fancyclopedia 2 Supplement ca. 1960:
Bob Tucker's sarcastic distortion of our name is pronounced with a sheep-like blat, to suggest the character of a group full of LMJ's and docile followers. Such sonic tricks, tho rare, have been applied to other uses; "around 1946", recalls Speer, "we were pronouncing 'NFFF' with a splutter followed by wiping the lips with the back of the hand."
