The phrase comes from everyday Russian speech, where calling someone Satan is an exaggerated way to call out heartless or devilish behavior rather than a literal religious claim. As a short WhatsApp style voice note it spread through forwarded chats and reposts, because the wording is instantly understandable to Russian speakers and the tone works even for viewers who only catch the emotion. It survives as a reaction clip for betrayals, cruel jokes and chaotic moments, often paired with a stunned face or a sudden cut to silence.
