Embistiéndola comes from the verb embestir, meaning to charge, ram, or attack. The -la suffix means "it" (referring to the moon).
In this song, it vividly describes the bull's passionate and almost aggressive pursuit of the moon. It's a strong, action-oriented word that captures the intensity of the bull's enamored state, making it memorable and unique to this narrative.
This song tells a charming story about a bull who is completely smitten with the moon! It's a really sweet and imaginative tale.
The lyrics describe the moon getting ready, "La luna se estaba peinando / Viendo espejos el río" [The moon was combing her hair / Seeing mirrors in the river], and the bull is secretly watching her, "Y un toro la está mirando / Y entre la jara escondío" [And a bull is watching her / Hidden among the rockrose]. He's so in love that when the moon disappears with the morning, "Cuando llega la alegre mañana / Y la luna se escapa del río" [When the joyful morning arrives / And the moon escapes from the river], he charges into the water, "El torito se mete en el agua / Embistiéndola al ver que se ha ido" [The little bull goes into the water / Charging at it when he sees she's gone]. He even abandons his herd at night for her, "Y ese toro enamorado de la luna / Que abandona por la noche la manada" [And that bull in love with the moon / Who abandons the herd at night]. It's a beautiful image of devotion, with the stars bathing him in silver and the mountains blessing him.
