Apsik is the Polish written form of a sneeze sound, similar to achoo in English, while o kurwa is a common Polish expletive used here as a shocked reaction. Combined, the phrase spread online as a short soundboard and meme clip because the meaning is clear even to listeners who do not speak Polish. The sneeze explains the setup and the swear delivers the payoff, so creators reuse it for fails, surprises and exaggerated everyday mishaps across gaming and reaction edits.
