Veneno literally translates to "poison". It's a dramatic and intriguing word that adds a layer of intensity to this romantic song.
In the lyrics, Christian Nodal asks his former lover which kisses she misses more: "Aquellos tiernos o los que llevan veneno" (The tender ones or the ones that carry poison). He uses veneno metaphorically to describe kisses that were wild, dangerous, and perhaps even a little toxic, but utterly unforgettable. This powerful imagery makes it a very memorable word to learn.
Mexican singer Christian Nodal stays up late scrolling through old photos and videos, and he is convinced his ex is doing the exact same thing. Instead of crying quietly into a pillow, he calls her out. He asks her directly: "De los besos que te di amor, ¿a cuál de todos echas más de menos?" ("Of all the kisses I gave you, love, which one do you miss the most?"). He walks through the whole collection—the sweet ones, the wild ones with no brakes, and the ones laced with "veneno" ("poison"). He refuses to believe she simply forgot about them.
The real bite comes when he calls out her sudden amnesia. He reminds her, "Si tú solita fuiste quien me dio luz verde" ("If you were the one who gave me the green light all on your own"). In Spanish, giving "luz verde" means giving someone permission or encouragement to make a move. He follows that up with pure Mexican sarcasm: "Ahora resulta que hasta la memoria pierdes" ("Now it turns out you're even losing your memory"). It is a hilariously cocky heartbreak song. He bets everything that while she pretends to be over it, she spends her nights biting her lip and thinking about him.
