The exact source of this clip is not clearly documented, so it is best understood as a short French phrase that has circulated online as a standalone meme sound rather than a line tied to a widely known film or show. Its appeal comes from how instantly it names a full working day, making it easy to reuse across short videos about jobs, school and adult routine. Because the phrase is short, direct and easy to translate in a caption, creators keep returning to it whenever they want a quick, relatable shorthand for monotony.
