John Cena is a WWE wrestler whose entrance and catchphrase made his name instantly recognisable far beyond wrestling fans. Online, editors turned that recognition into a joke by dropping his name and theme into unrelated videos, often right at the moment of a surprise or interruption. The elongated shout is a variation on that gag, stretching the announcement until it becomes the punchline itself. Because the reference needs no explanation, it still works in short-form edits, reaction videos and prank clips where a sudden, larger-than-life entrance sells the joke.
