It's really more the way he delivers it. It's hard to translate it and make it make sense but loosly it says
My riflfle that kills pointed strait at your head/
From your mom to your dirty whore, it's too late to Charrete/
Just because you stopped playing doesnt mean the game is over/
I'd need a Parisian to translate the "charrette" part because what it means to me doesnt make sense there. Might be some Parisian slang. Just like various english speaking countries have different slangs, so do french.
Kinda feeling the hook tho.
but overall the lyrics are like ..meh. I've heard much better french rappers than this
