The phrase co to jest is everyday Polish for what is this, and this recording, credited to Bałagany Na Bani, uses a profane intensifier that turns it into what the hell is this. Short Polish shouts like this circulate widely on soundboards because the emotion reads clearly even to listeners who do not speak the language. The clip has settled into use as a compact bewilderment reaction, shared in gaming, chat and video edits whenever something makes no sense at first glance.
