Mete le flouu is a French phrase that translates roughly as put the blur on it, and online it has become shorthand for censoring something in a video. Creators use the clip as an audio cue for pixelation, face blurring, and playful concealment, especially in short-form edits where a single spoken line can carry the joke. Because the phrase itself explains the edit, it works even for viewers who do not follow the original trend, and its short length has helped it circulate as a reusable sound for memes, reaction clips, and parody edits.
