The line comes from James Cameron's Titanic, released in 1997, when an elderly Rose looks back on the ship's sinking and says that eighty-four years have passed since that night. The moment became a shorthand for the passage of time, and slowed edits later gave it a second life on TikTok and in short-form videos, where the stretched delivery makes a wait, a reunion or a nostalgic flashback feel even longer. Its staying power comes from that simple setup: everyone recognises the reference, even without seeing the film.
