The sound comes from John Cena's WWE entrance theme, The Time Is Now, where the opening chant introduces the wrestler before his theme's hip-hop beat begins. Because Cena became one of WWE's most recognisable stars, the short intro travelled far beyond wrestling, becoming a shorthand for a big entrance in online videos. Creators now use it whenever a reveal needs instant recognition, turning the familiar chant into a punchline that works even for viewers who have never watched wrestling.
