The line comes from the cult French comedy La Classe américaine, where George Abitbol is presented as the classiest man in the world, and his understated put-down fits that deadpan persona perfectly. Clips from the film have circulated for years among French-speaking viewers, who reuse its most quotable lines as reactions to bad behaviour online. Because the insult is polite on the surface and cutting underneath, it works in both French and subtitled edits, and it has stayed popular as a short, instantly recognisable reaction sound.
