Rabiboche is a colloquial French verb meaning to 'patch things up' or 'reconcile', often after an argument or disagreement. It's a less common, more informal word than synonyms like réconcilier.
In the song, the line "Je reviens, je rabiboche" (I come back, I patch things up) suggests a recurring cycle of conflict and reconciliation in a relationship. This word choice adds a touch of everyday realism and emotional complexity to the lyrics, making it quite engaging.
"HS" is French slang for hors service, meaning broken down, knocked out, done, and Styleto builds the whole song around a boxing match that's really a breakup. She opens flat on the mat: "Battue" [Beaten], "J'suis pas sur le ring, j'suis déjà battue" [I'm not even in the ring, I'm already beaten]. The anxiety that follows is physical, not abstract: "La tête dans l'sac, sac sous l'oreiller" [head in the bag, bag under the pillow], like she's trying to smother the noise in her own skull before the fight even starts.
The chorus turns it into an actual bout against her own heart. "Sous les coups, droite, gauche / Je sens le sol qui s'approche" [Under the blows, right, left / I feel the ground getting closer] is the knockdown; "Un pas de côté / Qui tombera le premier?" [a step aside / who's going to fall first?] is her trying to dodge instead of go down. She doesn't stay on the floor for long: "Je reviens, je rabiboche / Mon cœur en chantier" [I get back up, I patch things back together / my heart's a construction site], which isn't fixed so much as still under repair. By the bridge she's swinging first: "J'enfile mes gants, je vais t'casser la gueule" [I put my gloves on, I'm going to smash your face in], and that's where the title lands hardest, "Hs, GG, KO" is the exact language off a fighting game's end screen, dropped straight into a love song.
