Menteuse translates to "liar" and specifically refers to a female liar. It's a strong and direct word that immediately sets the tone for the song's narrative.
In the context of the song, the artist uses menteuse to describe a woman who has deceived him, leading to heartbreak and betrayal. The repetition of this word emphasizes the central theme of dishonesty and makes it a memorable and impactful choice for learners.
KeBlack spends this whole song handing a label back. The hook sounds almost bored about it: "Elle c'est une menteuse elle est là pour plaisanter" (She's a liar, she's just here to joke around). Then comes the line that actually stings, "J'l'avais senti" (I'd felt it), because he saw it coming and stayed anyway. What he wants on the record is a distinction: "Je n'suis pas un voleur, encore moins un menteur" (I'm no thief, even less a liar). She tells stories about him, and he says the stories are hers.
The verses fill in what broke. They were building something real, "une famille on voulait fonder" (we wanted to start a family), before it turned into "elle a appelé les condés" (she called the cops) and a reputation he cannot shake off. By the last chorus there is no betrayal left to be angry about, only a person worn down: "j'ai perdu l'envie de t'aimer" (I lost the urge to love you). Between the verses the track just drops into "Oh-nana, oh-nana", a shrug over an Afro-trap loop, which is about the temperature of the entire song.
