The clip comes from the default style of alarm tone associated with older Xiaomi phones, shared here as a second variant credited to Bruni AFX. Its Russian title frames the alarm as shouting, which matches how Russian-speaking meme pages use it for someone who will not wake up, a joke the short note about poor Vadim hints at. Online it spread as a reaction sound rather than a practical alarm, because fifteen seconds of relentless ringing is funnier and more annoying than useful for actually getting up.
