The phrase draws on John Cena’s theatrical introductions as a WWE wrestler and his entrance theme, “The Time Is Now.” This particular meme format developed from a radio prank call that circulated widely online in 2014, then helped inspire the Unexpected John Cena trend during 2015. Creators inserted the announcement and music into unrelated videos as a sudden interruption. A longer John Cena reveal offers the same joke with a more extended delivery. The format remains recognizable because its buildup and musical blast communicate the punchline almost instantly.
