John Cena is a WWE wrestler whose entrance music, The Time Is Now, became the backbone of a viral prank format in the mid-2010s. Editors would splice the shout and brass fanfare into ordinary clips, from phone calls to news reports, so Cena appeared to interrupt everyday life. The format spread through Vine, YouTube and later TikTok because the reveal was instantly understood even without context. Years later it remains a shorthand for an absurd, triumphant entrance, reused whenever a creator wants a familiar shock instead of a subtle joke.
