The phrase comes from everyday French and translates loosely to yeah, that's what I needed, which explains why the clip travels well as a reaction sound online. It is credited in its file tags to Moubarak under a slightly different title, but its wider source is not clearly documented. Instead of a film or show quote, it has spread as a standalone viral voice clip, shared on soundboards and in edits where a relieved, satisfied reaction is funnier and more expressive than a simple yes or thank you.
