Pneumonoultramicroscopicsilicovolcanoconiosis 

Pneumonoultramicroscopicsilicovolcanoconiosis is a lung disease that is caused by inhaling fine silicate or quartz dust causing inflammation inside the lungs. A boring long word with a boring definition, though at least we can seem cool if we pronounce it and act smart.

Pneumonoultramicroscopicsilicovolcanoconiosis is the diagnosis my doctor gave me last year. I am better and good at pronouncing the word to seem cool and smarter too.
