The line comes from Jujutsu Kaisen, the Japanese anime and manga series whose characters often speak about duty, exhaustion, and the cost of relentless work in unusually direct terms. It spread online as a standalone reaction sound because its wording is simple, instantly understood, and easy to place over everyday footage. It is now used far beyond anime edits, especially in short videos about jobs, school, and burnout, where a calm, matter-of-fact verdict feels funnier and more honest than an exaggerated complaint.
