Where did hippopotomonstrosesquippedaliophobia come from?

Hippopotomonstrosesquippedaliophobia is a humorous term coined to describe the fear of long Words. The term combines "hippopotamus," "monstrous," "sesquipedalian" (which means long Word), and "phobia" (fear). It appears to have been created as a form of ironic humor, as the Word itself is quite long and unwieldy, reflecting the very fear it describes. Its origins are not tied to any clinical recognition but rather to playful language use.
