Several Latin stem words strung together as a joke by a student in Eton College in the 18th Century. The list came from a grammar book that listed a Latin word set in which all meant “little or no value.” These words were: flocci, nauci, nihili, and pili (with –fication at the end to make it a noun.)
flocci – floccus (a whisp or piece of wool)
nauci – naucum (a trifle)
nihili – nihilism (nothing)
pili – pilus (a hair)
In essence, they all mean little, nothing, or worthless. And quite obviously, this word is fun because it sets an example of a really long word.
