Juguete literally translates to "toy." While it's a common word, its use in this song is particularly striking and emotionally charged.
In "Tu Juguete," the singer uses it metaphorically to express feeling used and discarded in a relationship. He sings, "Pero yo fui tu juguete" (But I was your toy), conveying a sense of betrayal and heartbreak, as if his emotions were played with and then thrown away. This poignant usage makes it a powerful and memorable word in the context of the song.
J Alvarez opens with a confession: he didn't buy into love at all until she showed up. "Yo no creía en el amor" ("I didn't believe in love"), he admits, and for a while the gamble paid off: "Había luz, había color" ("There was light, there was color"). Then the wreckage. The hook spells out the whole song's verdict in four words: "Pero yo fui tu juguete" ("But I was your toy"). He wasn't a partner, just something she played with until she got bored.
The back half names what got broken. "Tiraste a la basura el corazón" ("You threw my heart in the trash") is about as blunt as reggaeton gets, and "Siento que nuestro amor se lo llevó el viento" ("I feel that our love was carried away by the wind") repeats three times because he keeps landing on the same conclusion: there's nothing left to fix, only to accept.
