Online, the phrase is best known as the notice shown when a post, video or story can no longer be opened, which is why creators have turned it into a shorthand joke for missing or removed material. Instead of explaining a broken link or a deleted upload, they let the familiar wording do the work, signalling to viewers instantly that something expected is gone. It works across reaction videos, edits and short skits because almost everyone who uses social media has met the same dead end, making the reference easy to recognise without any extra context.
