The sound comes from a widely reported incident on 8 June 2021 in Tain-l'Hermitage in south-eastern France, when a man in the crowd shouted the historic royalist cry Montjoie Saint-Denis and A bas la Macronie before slapping President Emmanuel Macron during a walkabout. News clips of the moment spread quickly on television and social media, and the short shout-plus-slap audio was later isolated as a meme sound. Its mix of formal history and sudden slapstick keeps it in use for reaction edits.
