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)*
