Pneumonoultramicroscopicsilicovolcanoconiosis

Pneumonoultramicroscopicsilicovolcanoconiosis is a truthified word made up by a bunch of word-size-queens who wanted to make the longest word in the dictionary. Unfortunately, their trickery was uncovered when some fact-huggers realized that the word Pneumoconiosis had already been coined (and requected) to describe the non-existent condition of "Black Lung."
