¿De dónde viene la expresión malagueña “merde John”?

What does “merde John” mean in Málaga Spanish?

A piece of Malagueño folk etymology — a popular legend, not documented history: when Napoleon’s army reached Málaga around 1810, locals were said to fling French insults back at the troops — but mangled the grammar. Instead of the correct “gens de merde” (people of filth), they reportedly said it reversed, “merde John,” filtered through Spanish phonetics. The story is the popular origin given for the regional slur “merdellón,” for a coarse, loud, slovenly person.

Real French word order would be gens de merde; the charm of the legend is precisely the mistake. Historians flag competing versions — some date it to Felipe V’s French courtiers a century earlier, others say the French coined it for the locals. Treat it as etimología popular, not settled fact: a vivid example of how a foreign phrase, mispronounced, can fossilise into a homegrown insult.
