hippopotomonstrosesquippedaliophobia 

Ironically, the fear of long words.

"sesquippedalio" relates to long words
"phobia" is an irrational fear
"hippopoto" and "monstro" (short for hippopotamus and monster) exaggerate the length of the word

synonym: sesquippedaliophobia means exactly the same thing

alt spellings: "pedalio" instead of "ppedalio"

guy: I have hippopotomonstrosesquippedaliophobia. *(guy starts hyperventilating)*
