Chambear is a colloquial and very common verb in Mexican Spanish that means "to work" or "to hustle." It's a more informal and often more energetic way to say trabajar.
In "Chequen El Porte," the lyric "mis socios saben que soy bueno pa chambear" (my partners know I'm good at hustling/working) highlights the speaker's dedication and skill in his business dealings. It gives insight into the character's work ethic and the informal, street-smart tone of the song.
Adriel Favela's "Chequen El Porte" is all about showing off how far he's come! He starts by telling us to "Chequen el porte, cabeza a rapa la Ropita medio aguada se ve un rolex con Diamantes" [Check the look, shaved head, baggy clothes, you can see a diamond Rolex]. He's serious about business, saying "Pa los negocios seriedad y buena vibra así salen bien los jales" [For business, seriousness and good vibes, that's how jobs turn out well]. He even throws shade at those who doubted him, remembering how people said he'd "nunca saldría adelante, el que dijeron que jamás iba a triunfar" [never get ahead, the one they said would never triumph].
He's definitely enjoying the good life now, with a good "toque" [vibe] that makes him feel good, and enjoying tequila to relax. He's ready to party, saying "Tengo ganas de enfiestarme" [I want to party] and assures us there's plenty of money to spend. He also mentions a past where he wore an "uniformé... ese color anaranjado con los homies en la grande" [uniform... that orange color with the homies in the big house], specifically mentioning "Mi celda la numero 80 letra E" [My cell number 80 letter E] and writing letters to family. But he keeps his "frente en alto como me enseñó mi apa" [forehead high like my dad taught me]. He's still humble though, with "Negros los converse, siempre sencillo una camisa de cuadritos pa no perder la costumbre" [Black Converse, always simple, a plaid shirt so as not to lose the habit], and he's good at making money, with "varias inversiones" [several investments] and his partners knowing he's good at "chambear" [working].
