The phrase is Polish for 'and it was going so well', and as a sound it circulates online mainly as a short reaction clip for moments when success turns into failure. Creators tend to use it without needing the original context, because the meaning is clear from the tone alone and the line works across gaming, cooking, DIY and everyday mishaps. Its appeal is its understatement: instead of shouting about a disaster, it calmly notes that everything had been fine, which makes the ending feel funnier and more relatable.
