Chambear is a very common slang verb in Mexico and other parts of Latin America that means "to work," often with the connotation of hustling or grinding.
It comes from the noun chamba (a job or gig). In the song, Junior H explains his backstory, singing that "el viejo lobo... se puso a chambear" (the old wolf... started to work/hustle) to make things happen. It's a fantastic, everyday word that will make your Spanish sound much more natural and is a perfect example of the real-world vocabulary you can learn from music.
Junior H kicks this song off by calling himself the "Viejo lobo en la manada" (Old wolf in the pack), letting everyone know he's the experienced leader. He warns any younger rivals, or "cachorros" (pups), that they can't compete with him. The main idea comes from the title line: "Ando como Jordan" (I'm like Jordan). He's comparing himself to the basketball legend Michael Jordan, meaning he's at the absolute top of his game, successful and unbeatable. This isn't just about skill; it's about a lifestyle where "La feria no se acaba" (The money doesn't run out) and the party only stops when there's no cash left to throw away.
What makes this song great is how direct and self-aware he is. He brags about "gastando el dinero / Chingando modelos" (spending money / f*cking models) and then immediately says, "y estoy bien culero" (and I'm ugly as hell). It's a funny, blunt admission that his success isn't about looks. He calls himself "El malnacido que falló en la escuela" (The bastard who failed in school), but now he's buying thick chains to fill a void he feels inside. He even gives a reason for his hustle: he wanted to get out of his neighborhood and help his sister go to school. It's a mix of big boasts, dark humor, and a little bit of heart.
