**Veneno** literally translates to "poison". It's a dramatic and emotionally charged word that you don't find in every song.
In "Lo Vas A Olvidar," Billie Eilish uses veneno metaphorically to represent the toxic feelings and emotional damage remaining after a painful breakup. The word is so central to the song's theme of hurt that it's used in both the Spanish and English lyrics, making it a powerful and memorable word to learn.
Lo Vas A Olvidar drops listeners into that hazy moment right after a breakup when your mind keeps circling the same questions: Do you still miss me? Do you regret what happened? Can love measured in extremes ever last? Billie Eilish and Rosalía trade Spanish and English lines like late-night voice notes, confessing how a once-intoxicating relationship has soured into “veneno” (poison). The repeated hook “¿Lo vas a olvidar?” presses on the bruise of memory, asking whether either of them can truly let go or if the hurt will linger in silence.
Over minimalist beats and echoing vocals, the song explores that fragile balance between pride and vulnerability. One moment they feel divine, the next they’re shattered, reminding us that love isn’t a steady march but a series of trembling steps. By the end, both singers face the truth: moving on is as much about reclaiming self-worth as it is about saying goodbye. Their whispered “besitos” (little kisses) land like an ironic farewell—tender, yet final—inviting listeners to decide for themselves whether to keep holding on or finally hit erase.
