Joueur du Grenier, created by Frédéric Molas, began in 2009 as a French YouTube series reviewing old and frustrating retro video games with angry, theatrical humour. Short extracts from those videos later circulated on soundboards and in French speaking meme communities, where familiar catchphrases became instant reactions. Mais oui survived because it needs no explanation for French speakers and still reads clearly to others through its tone. It remains popular for streams, edits and group chats where a knowing, exaggerated yes says more than a written reply.
