Atrévido means 'daring' or 'bold'. It's a dynamic adjective used to describe someone who isn't afraid to take risks or speak their mind.
In the song, the singer makes a provocative suggestion and then immediately says, "discúlpame si sueno atrevido" (excuse me if I sound bold). This playful apology for being bold is a key part of the song's flirtatious and confident charm, making you wonder just what he said!
Peso Pluma gets straight to the point in "Tu Con El". He's remembering a wild night with someone who's already in a relationship. He recalls "esa noche loca que pasamos encerrados" (that crazy night we spent locked up together) with her phone on airplane mode, totally cut off from the world. It's clear this isn't a one-time thing, as he sets up another meeting: "Te miro a las diez como la otra vez" (I'll see you at ten like the other time).
He lays out the rules of their secret affair with some incredibly blunt lines. He doesn't care about her boyfriend at all. He sings, "Me vale madres saber qué haces tú con él" (I don't give a damn what you do with him), as long as she still makes time for him. He even says he's fine with her sleeping with her partner, so long as she's also with him. It's a bold and direct take on a complicated situation, where he's willing to play the game just to keep seeing her.
