Baptisé literally means "baptized," often referring to a religious ceremony. However, in a broader sense, it also means to "name" something or someone, especially for the first time.
In this song, the word is used to describe the act of giving names to hurricanes and storms. The lyrics question who gives these names and if the storms themselves like their new "prénoms" (first names), making it a unique and thought-provoking use of a common word.
Have you ever wondered who names hurricanes? MPL certainly has! In "Joséphine," he playfully questions the whole process, asking, "À ton avis, d'où vient le nom?" [In your opinion, where does the name come from?]. He finds it a bit humiliating for a powerful storm to get a human name, thinking, "Un nom d'humain, pas étonnant Qu'elles cassent tout" [A human name, no wonder They break everything]. It's a funny thought, imagining the storms themselves being annoyed by their new monikers!
MPL also wonders if these names somehow predestine the storms, making them better or angrier. And what about the people who share those names? He asks, "Et les gens qui ont ces prénoms de tempêtes? Ça les dérange pas?" [And the people who have these storm names? Doesn't that bother them?]. It's a quirky and thought-provoking look at something we rarely consider, all wrapped up in a catchy tune. He even jokes at the end, "Et au beau milieu d'un océan On a baptisé un ouragan Sûr qu'il n'en demandait pas autant" [And in the middle of an ocean A hurricane was baptized Surely it didn't ask for so much]. It's a fun, imaginative take on a serious natural phenomenon!
