The sound comes from The Babadook, the 2014 Australian horror film directed by Jennifer Kent about Amelia and her young son Samuel. In the scene Amelia loses patience with Samuel's fearful, disruptive behavior and snaps the line before screaming. Clips of the exchange spread on YouTube and TikTok as a reaction meme, and editors began sharing this clean version without the scream so the quote could loop or sit under other footage. Its popularity comes from how universal the frustration sounds outside the horror context.
