Tú me enchinas la piel is a beautiful Mexican-Spanish phrase that translates to "you give me goosebumps". The verb enchinar specifically refers to the physical sensation of your hair standing on end from a strong emotion like love or excitement.
In this song, Carla Morrison uses this line to express the intense, almost electric physical reaction she has to the person she loves. It’s a wonderfully poetic and specific way to describe a feeling that goes beyond words, capturing the raw emotion of the song.
Carla Morrison's "Compartir" is a beautiful list of all the simple, everyday things you want to do with someone you love. She isn't asking for grand gestures; she just wants to share her life. She sings, "Quiero compartir mi silla contigo" (I want to share my chair with you) and "Quiero reír y llorar con tus ojitos" (I want to laugh and cry with your little eyes). It's a song about wanting to experience every part of life, big and small, with one special person, even dreaming of "caricias contigo" (caresses with you).
But there's a catch. She reveals that "No es nada fácil, estar tan lejos de ti" (It's not easy, being so far from you). This person isn't there with her. The song then describes the intense physical reaction she has to them, even from a distance. She says, "Tú me enchinas la piel" (You give me goosebumps) and "Vuelvo a respirar / Y comienzo a temblar" (I breathe again / And I start to tremble). It’s a powerful declaration of how this person's existence alone is enough to affect her completely, making her love stronger with their every move.
