The sound comes from WWE, where John Cena became one of the company's biggest stars in the 2000s with his entrance theme 'The Time Is Now'. The line 'And his name is John Cena!' became a viral meme around 2015, when prank videos and edits would blast the announcement and theme over unrelated footage for a surprise Cena appearance nobody expected. The format spread widely on Vine, YouTube, and later TikTok, and the clip remains a staple reaction sound for unexpected entrances and reveals.
