The line comes from the 3 May 2017 televised debate between Emmanuel Macron and Marine Le Pen ahead of the French presidential election run off. Macron used the old expression poudre de perlimpinpin, traditionally a quack remedy with no real effect, to dismiss his opponent's proposals as empty. The phrase surged in French media and online afterwards, spawning remixes, parodies and reaction clips, and it remains a widely recognised shorthand in France for snake oil, political bluffing and promises that sound magical but lack substance.
