Castigo literally translates to "punishment". While this might sound negative, in the world of reggaetón it's often used as a playful and flirty slang term for intense passion.
When Feid sings, Pasar la noche dándote castigo (Spending the night giving you punishment), he's using this double meaning to describe a wild, romantic night. It's a perfect example of how context can completely change a word's meaning in music, making it a very intriguing word to learn!
Colombian hitmaker Feid delivers a moody reggaeton anthem about obsessing over an ex who has supposedly moved on. He admits to typing out texts he never sends and complains that while he is sweating in Miami, his heart is ice cold. Even though both of them pretend it is over, he reminds her of their lingering connection with a classic line: "Se te olvidó que tú y yo nos dimos un beso después de habernos despedido" (You forgot that you and I kissed after saying goodbye).
He pairs wounded pride with typical nightlife swagger, brushing off her other suitors by calling them his "hijos" (sons—a slang way to say they are amateur copycats). He also watches her flaunt gym photos during a nonstop "Hot Girl Summer" while he drops devil emojis in her comments. Between partying, passing a vape, and leaving behind his signature sunglasses so she cannot forget him ("Quédate con mis lentes / Solamente pa' que me recuerdes"), the track blends late-night club energy with total heartbreak.
