pneumonoultramicroscopicsilicovolcanoconiosis is a word that refers to a lung disease contracted from the inhalation of very fine silica particles, specifically from a volcano; medically, it is the same as silicosis and, yes, silica i that stuff that precious wolf baby Yuki eats in Wolf Children. (it keeps stuff dry, like your very salty dried seaweed) Often used by Avis who think they're smarter than everyone else and will spew random facts to impress their crush, usually named Tatum

The longest word in the dictionary that can mean a certain lung disease caused by inhaling fine silica dust from volcanoes, or it can be used as a fun word to say because its so incredibly long. WARNING. THIS WORD IS LONGER THAN SUPERCALIFRAGILISTICEXPIALIDOCIOUS BY A FEW SYLLABLES. Hope you don't have Hippopotomonstrosesquippedaliophobia.

Me: "Did you ever hear the longest word ever? "
Person Who Hasn't Read This Yet: "Yes, I think its Supercalifragilisticexpialidocious."
"Well you're WRONG, its Pneumonoultramicroscopicsilicovolcanoconiosis. HAH.
