Faille literally translates to "flaw" or "fault," but it can also mean "loophole" or "weakness." It's an interesting word because it suggests a hidden vulnerability or an unexpected opportunity.
In the context of the song, Josman raps, "J'ai trouvé la faille, pour faire de la maille" (I found the loophole, to make money). Here, "faille" refers to discovering a clever way or a secret advantage to achieve success and wealth, making it a compelling and strategic word choice.
Josman's "High Life" throws us right into his world, where he's doing his own thing, feeling high, and observing others with a bit of disdain. He's got "la grosse tête dans mon joint, j'suis high" [my big head in my joint, I'm high], and his brain feels like a "Rubik Cube." He's not impressed by others, finding them "ridicules pour de vrai" [ridiculous for real].
This song is all about Josman's hustle and his journey. He's chasing money because he doesn't want to "finir dans la rue" [end up in the street], and he's seen a lot of life, from "violence, douleur et douceur, amour et haine" [violence, pain and sweetness, love and hate]. He's found his own way to "faire de la maille" [make money], and he's living his version of the "high life," even if sometimes his fridge is empty and he's just trying to get by. He's young, frustrated ("j'ai l'seum"), but determined to succeed on his own terms, dreaming of a "vie d'rêve" [dream life] without needing a gold chain.
