The sound comes from the German-language meme format built around the caption about buying a 0€ alarm clock from Temu. The joke spread in short-form videos and soundboards where ultra-cheap online shopping hauls are mocked for arriving broken or useless. Rather than a clean alarm tone, creators kept the long, defective ringing because its failure is the entire gag. It is now reused whenever a bargain product, morning routine, or wake-up attempt goes embarrassingly wrong.
