Mañoso is an interesting word that can have several meanings depending on the context, often implying someone is cunning, tricky, or has a knack for getting their way.
In this song, the artist uses it to describe himself in a playful yet confident way, suggesting he's street-smart and perhaps a bit mischievous, especially when he sings, "Que ando de perro, que soy bien mañoso" (That I'm a dog, that I'm very tricky/sly). It adds a layer of personality to the lyrics, making it more engaging than a simple, common adjective.
In "COCO," Tito Double P addresses a lover, acknowledging his wild reputation. He's heard people are calling him loco (crazy) and mañoso (sly), and that her mom thinks he looks like a cholo (gangster). He playfully blames his infatuation on her, saying his behavior is the "fault of your photos."
Despite the rumors, he insists he has his own style: he's handsome, has money (feria), and class. He reminds Coco that she always knew he loved a bit of chaos (desmadre), so she shouldn't be surprised. He balances his tough, bélico image with romantic promises of flowers, Louis Vuitton gifts, songs, and vacations, showing a softer side beneath the rebellious exterior.
