Piquete is a popular slang term, especially in the Caribbean, that means 'swag,' 'flair,' or a stylish and confident attitude. While its literal meaning can be 'sting' or 'prick,' in music and street culture it's used to describe a person's unique and impressive style.
In the song, Bad Bunny boasts, "Hoy salí con piquete de artista" (Today I went out with an artist's swag), using the word to define his cool and defiant fashion sense that sets him apart. It's a key piece of slang to understand if you love reggaeton!
Bad Bunny has a very simple message for anyone who doesn't like his style: "Si no te gusta no tienes que mirar" (If you don't like it, you don't have to look). This whole song is a super confident anthem about dressing exactly how you want and ignoring the haters. He makes it clear that his choices are his own and no one else's business, especially since "tú no lo vas a pagar" (you're not going to pay for it). It's a blunt and powerful statement about self-expression.
He backs up his confidence by pointing to his success, contrasting his critics with the fact that he's on magazine covers. He even gets a little funny and specific, saying he'll dress "de Panda como Jack Black" (like a Panda like Jack Black) if he feels like it. He suggests that people who criticize others' style might have had their own creativity crushed as kids, saying "Quizás la tuya mató tus fantasías" (Maybe yours [your mom] killed your fantasies). Ultimately, he states that his worth has nothing to do with his clothes: "Mi valor no se basa en cómo yo me vista" (My value isn't based on how I dress).
