The sound borrows from the long-running internet joke around John Cena, whose name became a shorthand for an unexpected entrance after clips of his theme and sudden appearances spread across wrestling broadcasts, video platforms and social feeds. Pairing that shout with a dubstep wub gives the old gag a newer, louder punch, which is why editors reuse it for reveals rather than straight wrestling footage. Its short length makes it easy to drop over a single cut, and its recognisable rhythm keeps it working even for viewers who have never watched a match.
