The sound comes from a Pringles commercial starring Bill Hader, who turns on a character named Kevin and delivers the line as an exasperated outburst. Clipped from the ad, it circulated on soundboards and in meme edits as a universal tell someone their input was not invited. Its appeal is similar to a bruh reaction, short, instantly readable and reusable in almost any conversation where an opinion arrives completely unprompted and unwanted.
