John Cena is a WWE wrestler whose entrance music became instantly recognisable to wrestling fans long before it spread as an internet meme. Online creators began cutting the entrance into unrelated videos, so a calm scene would suddenly break for Cena's theme and crowd reaction, turning an ordinary moment into a surprise gag. That prank format travelled across video platforms and short-form edits, where the sound now works even without wrestling context. Its staying power comes from that shared recognition: most viewers know a reveal is coming the moment the music starts.
