The phrase has long been a shorthand for dramatic devotion in popular music and film, which is why a short sung version travels so easily online. Creators reuse it as a ready-made emotional cue, dropping it into relationship edits, reaction videos and parody clips where the sincerity itself becomes the joke or the payoff. Its brevity helps too, since the whole sentiment fits into a few seconds and works without context, keeping it in regular use for anniversaries, farewells and light-hearted tributes.
