John Cena is a WWE superstar whose entrance theme, The Time Is Now, became famous far beyond wrestling when clips of his dramatic arena introduction were reused online as a surprise meme. The format exploded on Vine and YouTube in the mid-2010s, where editors would interrupt an ordinary video with his music and shouted name to fake a sudden appearance. That unexpected reveal structure proved endlessly reusable, and later TikTok creators kept it alive for entrances, pranks and heroic reveals, making the sound instantly recognisable even to people who never watched wrestling.
