The line comes from Fuze III, a French gaming YouTuber with a large French-speaking audience built around his Minecraft videos. Fans picked up his enthusiastic 'on adore le nucléaire' as a catchphrase and clipped it into a standalone meme sound. It spread through French meme pages and soundboards, where it now sits alongside the French meme song as recognisable French internet humour, and editors still drop it whenever a video needs an ironic cheer for anything atomic.
