John Cena is a WWE wrestler whose entrance theme 'The Time Is Now' became instantly recognisable for its opening trumpet fanfare. The 'and his name is John Cena' edit grew out of wrestling broadcasts and a viral radio prank format, then spread widely in 2015 across Vine and YouTube. Editors would build an unrelated scene, pause for the introduction, and cut in Cena where he did not belong. The format stayed popular because the fanfare is unmistakable and the setup works for any surprise appearance.
