Costear means 'to afford' or 'to pay for' something, often implying covering the expenses or costs associated with it. It's a more specific and nuanced verb than simply 'comprar' (to buy).
In "MALDITA POBREZA," Bad Bunny uses this word to express his deep desire to provide for his girlfriend despite his financial struggles. He sings, "Pero yo te quiero costear" (But I want to pay for you / afford you everything), highlighting his aspiration to buy her luxuries like Gucci, a house by the sea, and trips to France, even though he currently cannot. This word perfectly encapsulates the song's central theme of love, ambition, and the harsh reality of poverty.
Ever wanted to give someone the world but couldn't even afford a nice dinner? That's the whole mood of this song. Bad Bunny lays out his frustrations with being broke in a way that's both funny and super relatable. He repeats over and over, "Yo quiero comprarle un Ferrari a mi novia / Pero no puedo" (I want to buy my girlfriend a Ferrari / But I can't). He dreams of buying her Gucci, a house by the sea, and even Picasso paintings, but his reality is that he can't even afford a single beer, or "una chela". He calls it "Maldita pobreza" (Damned poverty), and says the only thing that makes him forget is when his girlfriend kisses him.
He gets pretty specific about his struggles, mentioning he studied for seven years but can't find a job in his field. This leads to a wild dream sequence where he robs someone, blows up the government building, and gets killed like a famous rapper. But here's the twist: his girlfriend shows up to his funeral driving a Ferrari. It's a perfect ending that flips the whole song on its head, mixing his dark frustrations with a sweet, almost surreal punchline.
