Garrapata literally translates to "tick", the small parasitic arachnid. It's a very unusual and memorable word to find in a song, especially in a romantic context.
In the lyrics, the singer uses it metaphorically when he says, "me puse como el chiste el monaguillo hay como una garrapata hasta que me dio esta canción." He's humorously comparing himself to a tick, implying he was persistent and wouldn't let go until he got the song he wanted. This unexpected use makes the word stand out and adds a playful, determined tone.
Nelson Arrieta's "Regálame Tu Amor (En Vivo)" featuring Ronald Borjas is a passionate plea for love, delivered with the raw emotion of a live performance. The song opens with Nelson sharing a fun anecdote about how he really wanted to record this particular song, even pestering Gustavo Aguado for it!
From the very first lines, the singer is begging for any piece of his beloved's affection: "Regálame tu amor" [Give me your love], "o la sombra de tus ojos" [or the shadow of your eyes], "o tu tiempo como ahora" [or your time like now]. He needs her presence to feel complete, confessing, "necesito tu presencia, necesito tu cariño, necesito" [I need your presence, I need your affection, I need you]. It's a powerful declaration of how much he relies on her, stating, "comprende que a tu lado soy yo" [understand that by your side, I am myself]. He even asks for a single tear, "regálame una lágrima siquiera porque necesito tener algo de ti" [give me at least one tear because I need to have something of you]. It's a really intense and heartfelt song about wanting someone back in your life.
