The phrase c'était sûr en fait is everyday French for saying an outcome was obvious all along, and this short recording circulates online purely as a reaction sound with no confirmed original source attached to it. It spread through soundboards and short video edits where creators needed a deadpan French response to predictable mistakes. Its appeal is the contrast between the calm wording and the frustrated meaning, so it keeps being reused for fails, spoiled plans and moments where the result was clear long before it actually happened.
