pneumonoultramicroscopicsilicovolcanoconiosis 

An inflammation of the lungs caused by microscopic grains of certain types of rock.

*NOTE* This word was actually coined in a deliberate attempt to be the longest word in the english language, although you would be hard-pressed to find it in the language dictionary as it is a medical/scientific term.

"Dude, now that I've learned how to spell antidisestablishmentarianism, what am I going to do to make people think I'm smart?"

"Quiet man, I'm trying to name this condition we discovered today. Its an inflammation of the lungs caused by microscopic grains of certain types of rock."

"Hey, I smell opportunity! How long could we make this word?"

"Pretty long...I suppose we could stretch it to pneumonoultramicroscopicsilicovolcanoconiosis"
