Iridocyclitis is a real medical term for inflammation of the iris and ciliary body, and its length and awkward spelling have made it a favorite example of a hard to pronounce word online. Short clips built around saying it and laughing spread on soundboards and in meme edits, where the joke is the struggle itself rather than any specific show or movie. It remains popular as a quick reaction sound for tongue twister fails, spelling challenges and moments when technical language suddenly sounds completely ridiculous.
