Dropped on soundboards as Lemus - Kessé qu'a dit là, the clip spread as a short French Canadian reaction rather than from a widely credited film or show. Kessé is a slurred contraction of qu'est-ce que, common in informal Quebec speech, which gives the line its local, everyday feel. Online, editors reuse it whenever dialogue turns weird, a take makes no sense, or someone confidently says something wrong, because the question sums up the viewer's own reaction in just over three seconds.
