Condena means "sentence," "conviction," or "condemnation," often used in a legal or religious context. It's a very powerful and dramatic word that you don't hear in songs every day.
In "Morena Canela," the singer uses it to describe the woman he desires: "Seduce, atrapa, tú eres la condena" (She seduces, she traps, you are the condemnation). He's poetically expressing that his attraction to her is an inescapable fate—one that is both thrilling and dangerous, like a curse (maldición) or karma.
Chino Pacas gets straight to the point in "Morena Canela." He sees a woman he calls a "Morena finita de piel canela" [fine, cinnamon-skinned brunette] post a photo online and immediately wants to spoil her. He's not shy about his intentions or his money, telling her "Pa' ti tengo la cartera llena" [For you I have a full wallet] and offering to buy her anything she wants. He presents himself as a classic bad boy, boasting that his scent is a mix of "problemas, Creed y mota cara" [problems, Creed cologne, and expensive weed]. It's a confident, maybe even arrogant, invitation to a wild night.
The song is all about intense desire and possession. He sees her as a beautiful temptation, calling her "Bebé, Lucifer" [Baby, Lucifer], and makes it clear he doesn't want anyone else talking to her. The lyrics get very bold with lines like "Hoy no llegarás a casa / Voy a robarte, y sí, es una amenaza" [You won't get home tonight / I'm going to steal you, and yes, it's a threat]. He's laying all his cards on the table, asking her who else can give her goosebumps the way he does.
