Khabat is a slang term, originating from Arabic, that means to be 'high' or 'stoned' from drug use. It's a word that reflects a certain street or urban culture often depicted in rap music.
In the song, the artist uses it in the lines "Mi-khabat, j'pense à toi" (Half-high, I think of you) and "Khabat, j'pense à toi" (High, I think of you). This suggests a state of altered consciousness where thoughts of a particular person (perhaps a lost love or a significant other) still dominate, even when under the influence. It's an interesting word because it's not standard French and provides insight into a specific subculture.
GLK's “Mbappé” is a flex track that borrows the footballer's name as shorthand for speed and status. The hook turns it into a boast about outrunning everyone else — “On les fait courir plus vite qu'Mbappé” [We make them run faster than Mbappé] — while the verses stack up cash and watches: “On fait du papel, on fait des euros” [We make papel, we make euros], “Le poignet est diamanté” [The wrist is diamond].
Underneath the boasting is a line drawn between loyalty and betrayal — “Tu parles aux condés, toi, tu collabores” [You talk to the police, you collaborate] — and a softer thread about a woman he keeps circling back to, Ninetta, even while insisting “Nan, revenir, j'peux pas” [No, I can't go back].
