Traicionero translates to "treacherous" or "betraying". It's a strong, evocative word that goes beyond simple betrayal, implying a deeper, more insidious deceit.
In the song, the singer vows to drink "cada gota de tu llanto traicionero" (every drop of your treacherous tears). This powerful imagery suggests that even the tears of the person who promised to return are not genuine, but rather a part of their deceitful nature, making the word particularly impactful in conveying the depth of the singer's pain and desire for revenge.
This song is a powerful story of heartbreak and the desire for revenge after a broken promise. The singer is reeling from a lover who promised to return but never did. Three winters have passed, and the wait has made his heart feel old. He sings, "Te llevaste mi fe, Mi penúltimo te quiero, Odiaste mi alma, Y mi autoestima, Está en el suelo" [You took my faith, my second-to-last 'I love you,' you hated my soul, and my self-esteem is on the floor]. Ouch!
But this isn't a song of just sadness. Oh no. The singer is determined to rise above it. He believes he'll eventually see his former love in the same broken state he's in now, crying "lágrimas de sangre" [tears of blood] and kissing the ground in regret. And then? He's going to drink "Cada gota de tu llanto traicionero" [Every drop of your treacherous tears] to see if revenge is as sweet as everyone says. It's a pretty intense promise, and you can almost hear the smirk in his voice when he says, "Chiquita, la venganza, La venganza es dulce, ora" [Sweetheart, revenge, revenge is sweet, now]. He's just waiting for the hook to bite!
