The coffee mug breaking sound is one of those everyday foley effects that lives in comedy editing. Rather than tracing back to a single film or meme, it grew out of stock sound libraries and user soundboards, where a clean shatter was always in demand for pranks and fail compilations. On video platforms it usually lands under clumsy skits, angry morning routines and kitchen disasters, doing the same job as a metal pipe clang or a SpongeBob fail sting: a quick audio punchline that makes a small accident feel bigger. Its five-second length makes it easy to drop without trimming.
