Eriza comes from the verb erizar, meaning to bristle or stand on end. It's often used to describe hair or skin reacting to a strong emotion like fear, excitement, or in this case, intense affection.
In the song, Olga Tañón sings, "Que se te eriza la piel y mariposas te bailan" (That your skin bristles and butterflies dance for you). This vivid imagery captures the physical sensation of being deeply moved by love, making it a memorable and evocative word.
Have you ever been so in love you feel a little bit crazy? That's the feeling Olga Tañón captures in "Esta Loca." The singer serenades her beloved under the moonlight, calling herself "esta loca"—this crazy woman who is dying for her partner. She asks if they feel the same intense emotions: the goosebumps (que se te eriza la piel) and the butterflies dancing inside (mariposas te bailan). It's a passionate declaration of a love that feels like a beautiful kind of madness.
The song is filled with romantic poetry. The singer imagines the moon as her backup singer and the sun getting jealous of her nighttime serenade. She doesn't just promise love for today; she promises a love that will last a lifetime. She sings about traveling through time to be with her partner even when they are old, showing a deep, timeless commitment. The core message is an invitation to let go and be carried away by this powerful, all-consuming love.
