Pain au chocolat and chocolatine refer to the same chocolate filled viennoiserie, but the preferred name splits France regionally, with chocolatine common in the southwest and pain au chocolat used in most other regions. The disagreement has existed in everyday speech for decades and turned into a recurring online joke, poll and meme topic as social media amplified the rivalry. Short audio clips quoting the choice are shared because the debate is instantly understood by French speakers, harmless to argue about, and easy to reuse for any stubborn either or argument.
