The sound comes from Vnutri Lapenko, known in English as Inside Lapenko, the Russian comedy web series created by actor Anton Lapenko. The series became widely shared around 2019 and 2020 for its retro Soviet style and its cast of eccentric characters, all played by Lapenko himself. Short lines like this greeting were clipped by fans and spread as a meme sound across social media and messaging apps, where Russian speaking audiences use it as a joking, familiar way to say hello to a friend or older man.
