Impetuoso is a poetic adjective that translates to "impetuous."
It describes a person or force that is powerful, rash, and acts on sudden impulse, much like a violent gust of wind. In the song, India uses this word in a vivid simile, "Como el viento impetuoso" (Like the impetuous wind), to characterize the man's volatile and unpredictable nature. It’s a dramatic word that perfectly captures his passionate yet destructive personality.
Puerto Rican singer India does not hold back for a single second in "Ese Hombre". She points directly at a guy across the room who looks charming, generous, and polite to everyone else, and immediately tears down his front. She warns us, "Ese hombre que tú ves ahí / Que parece tan galante... Sólo sabe hacer sufrir" ("That man you see right there / Who seems so gallant... Only knows how to cause suffering"). The entire track is an unfiltered warning from someone who knows his real personality inside out.
What makes the song so entertaining is how direct the insults get. India piles on descriptive words, calling him "un payaso vanidoso" ("a vain clown"), "un gran necio un estúpido engreído" ("a huge fool, a conceited idiot"), and someone who is "inseguro de sí mismo" ("insecure about himself"). He acts confident, but behind closed doors he is jealous without reason and rarely affectionate. By the end, the song turns into a direct confrontation with the line "Tú me engañaste y me traicionaste" ("You cheated on me and betrayed me"), declaring that the suffering is over and he is finally out the door.
