The line comes from Avengers: Endgame, released in 2019, where Morgan Stark, Tony Stark's young daughter, tells her father she loves him 3000. The phrase quickly became one of the film's most quoted moments and spread through fan edits, memes and social media tributes after the film's release. The French dubbed version, 'Je t'aime plus que trois fois mille,' circulates in the same kinds of emotional edits, especially among French-speaking fans. It remains in use because the line is instantly recognised as a shorthand for deep affection and farewell.
