Chaparrita is a charming and affectionate term of endearment, literally meaning "shorty" or "little one." While it refers to someone short in stature, it's used here in a tender and loving way, similar to "sweetheart" or "darling."
In the song, the singer repeatedly uses chaparrita to address the woman he loves, emphasizing his deep affection and admiration for her. It's a common term in Mexican Spanish, adding a culturally rich and endearing touch to the lyrics.
Fuerza Regida's "Mi Gusto Es" is a super fun song about being completely dedicated to what you love, no matter what! The singer is basically saying, "This is what I like, and only God can stop me!" He repeats, "Mi gusto es / ¿Y quién me lo quitará? / Solamente Dios del cielo me lo quita" [My liking is / And who will take it from me? / Only God in heaven will take it from me].
What he loves? A young woman! He's totally smitten and declares, "Mi gusto es / El amarte jovencita" [My liking is / Loving you, young lady]. He's so committed that he says he'll keep following her for kisses wherever she goes: "Yo te he de seguir los besos a donde estés" [I will follow your kisses wherever you are]. Even if people try to stop him, or as he puts it, "Y aunque me den de batazos" [And even if they hit me with bats], he's not giving up. It's a bold and passionate declaration of love and stubborn devotion!
