John Cena is a WWE wrestler whose entrance theme, The Time Is Now, has the ring announcer introduce him before his music hits. In 2015 the introduction became the Unexpected John Cena meme online, where videos would build normally and then cut suddenly to his name and theme at maximum volume. Clips spread across Vine, YouTube and meme pages, turning any unsuspecting subject into the punchline. It remains a staple reaction sound because the setup is instantly recognisable and the drop still feels absurd years later.
