Firmão is a colloquial and intensified form of firme, meaning 'firm' or 'strong'. The suffix -ão is an augmentative in Portuguese, often used to emphasize size or intensity, making it 'very firm' or 'standing strong'.
In the context of the song, the artist says, "Ah, eu 'to firmão com a minha de fé," which translates to "Ah, I'm standing strong with my faith." It conveys a sense of resilience and unwavering belief, making it an interesting and engaging word that reflects the song's assertive tone.
In "Sistema," Mc Kevin unleashes a raw and powerful critique of the world around him. He repeatedly asks a frustrated question: "What the hell is happening with the system?" He sees the world as a "dirty" place, full of "trash," and feels a constant need to protect himself, describing his "trigger" that doesn't fail. This isn't just aimless anger; it's a response to a world he feels is broken.
Amidst the chaos, Mc Kevin holds onto his faith, stating, "God is my guide and keeps me on my feet." He also calls out the fake people who suddenly appear now that he's successful, driving a Jaguar and living in a huge house. He dismisses these hangers-on, who "weren't there in the past" but now want to be by his side. The song is a defiant statement from someone navigating success in a world he doesn't trust, blending themes of frustration, self-defense, and loyalty.
