Abstinencia means 'abstinence' or 'withdrawal'. It's a powerful and somewhat unexpected word to find in a love song, making it very memorable.
In the lyrics, the singer uses it to describe the intense longing and suffering he feels from the absence of his loved one, comparing it to the painful experience of withdrawal: "Ahora sé lo que es vivir en abstinencia" (Now I know what it's like to live in abstinence). This metaphorical use elevates the emotional depth of the song, making it a truly unique and enticing word.
This song from Colombian group ChocQuibTown is a straight-up anthem for anyone trying to get over a breakup. The main character is having a really tough time and has decided the best solution is alcohol. He repeats the line "A veces tomo pa' olvidarte" (Sometimes I drink to forget you) because, as he says, "sinceramente duele recordarte" (honestly it hurts to remember you). Without his ex, he feels like "la soledad ganó el combate" (loneliness won the fight). It's a feeling of total defeat.
He admits he's not perfect, calling himself "un hombre con cien mil defectos" (a man with a hundred thousand flaws), but his feelings were real. He's so torn up that he makes a point to say his red eyes are "por llorarte y no por el whisky" (from crying for you and not from the whiskey). He's trying to forget, but he's also dreaming of her coming back and imagining his hand holding hers. It's a sad, honest look at how messy and painful heartbreak can be.
