John Cena, the WWE wrestler and actor, has used his entrance music for most of his wrestling career, and the wordless brass riff has become shorthand for an unexpected arrival online. The meme format, in which the music starts just before Cena or an ordinary person appears on screen, spread widely through short video platforms, where creators reuse it for reveals, entrances and surprise wins. Because the tune is recognised instantly without any lyrics, the instrumental version works even in short edits and remains a popular choice for comedic entrances.
