John Cena is a WWE wrestler whose entrance theme, The Time Is Now, was released in 2005. The dramatic announcer introduction and trumpet fanfare became the basis of the Unexpected Cena meme, which spread widely online in 2015 through Vine edits and a viral radio prank call expecting a different conversation. Clips would build quietly before cutting suddenly to Cena's music and name at full volume. The format stayed popular on YouTube and TikTok because the sound alone signals the interruption, even without any wrestling footage on screen.
