"action or habit of estimating as worthless," in popular smarty-pants use from c.1963; attested 1741 (in a letter by Shenstone, unpublished until later in the century), a combination of four Latin words (flocci, nauci, nihili, pilifi) all signifying "at a small price" or "for nothing," which appeared together in a rule of the well-known Eton Latin Grammar. The kind of jocular formation that was possible among educated men in Britain in those days. Just so, as in praesenti, the opening words of mnemonic lines on conjugation in Lilley's 16c. Latin grammar, could stand alone as late as 19c. and be understood to mean "rudiments of Latin."
