Il digère is French for he is digesting, and online the phrase is used figuratively for someone slowly processing something shocking, gross or hard to believe. As a short reaction sound, it circulates in meme edits and short-form videos where a spoken line can do the work of a caption, letting viewers recognise the feeling of needing a moment to take something in. Its appeal is not tied to one scene or show, but to that shared, uncomfortable pause, which is why creators keep reaching for it when a clip needs a dry, understated reaction rather than a loud one.
