There is no widely documented origin for this short chant, and it appears to circulate mainly as a user-uploaded soundboard clip rather than a line from a film, show, or song. Its appeal comes from the repetition itself, which turns a shortened fast-food name into a catchy, easy-to-quote gag. Online creators have picked it up for short-form videos and memes about cravings, drive-through runs, and snack choices, where a two-second sound can set up a joke without explanation. That simple, shareable format is why it keeps appearing in edits.
