Serpiente literally translates to "snake". It's a powerful and intense word used here as a metaphor for a dangerous and seductive lover.
In the song, Junior H sings, "Tú eres una serpiente que me ahoga" (You are a snake that chokes me). He uses this striking image to describe a person who is both intoxicatingly attractive and suffocating, capturing the complex and toxic nature of their relationship. This metaphor is the central theme of the entire song.
Junior H gets straight to the point in "SERPIENTE"—this is about a connection that's both irresistible and completely toxic. He's drawn back to someone he knows is bad for him, comparing her to a snake that's choking him: "Tú eres una serpiente que me ahoga y que no me deja ni respirar" (You are a snake that chokes me and doesn't even let me breathe). He knows they have no real future, admitting "La oportunidad de estar juntos se fue, creo que nunca volverá" (The opportunity to be together is gone, I think it will never come back).
Despite knowing how dangerous she is, he can't stay away. The song is a push-and-pull between recognizing the danger and giving in to the intense physical and emotional bond they share. One moment he's asking to forget their pasts and just act on their desire, and the next he's promising to be there for her in her worst moments. It's a complicated, messy situation about a love that feels both like a safe harbor and a deadly trap at the same time.
