Sah quel plaisir became a reusable French internet reaction thanks to singer Bilal Hassani, known for his flamboyant persona and Eurovision 2019 appearance for France. The phrase itself is casual French slang, where sah reinforces the feeling like saying honestly or truly. Clips of his expressive delivery circulated on French social media and soundboards, where users isolated this exclamation as a standalone meme sound. It remains popular because the cheerful wording can be applied ironically to almost any disappointing or mundane situation.
