Agüitado is a colloquial Mexican Spanish term that means 'down', 'sad', or 'bummed out'. It's a more informal and expressive way to say someone is upset or discouraged.
In the song, the artist says, "Creo que se han agüitado porque los arrebasé" (I think they got bummed out because I surpassed them). This word perfectly captures the feeling of envy or resentment from others who are upset by his success, making it a relatable and interesting piece of slang to learn.
FREESTYLE is Hermanos Espinoza taking stock out loud. Over a slow regional Mexican groove, the narrator counts what he has built and who helped him build it: his brother, his father, and a faith he keeps coming back to. The tone is less boastful than stubborn. He knows how fast he has moved bothers people, and he says plainly that he is not going to stop.
The hook carries the whole idea. "No, no soy normal, no sé qué me pasa / Pues le chingas más cuando hay hambre en casa" is a blunt explanation of the work ethic: you push harder when there is hunger at home. Everything else in the song, the full garage, the diamond cross, the flight to Japan, is measured against that memory rather than shown off on its own.
The last verse turns to what it cost. Friends thinned out, and some of the ones who stayed want a plate more than a person. He is twenty four, he has more than he expected, and he asks the people who never went hungry beside him to leave him be.
It closes on a spoken reading from Psalm 27, which is where the song has been pointing the whole time: light, salvation, and an army that can camp against you without shaking you.
