Yonqui is a Spanish slang term for 'junkie', referring to someone addicted to drugs. It's a strong and somewhat provocative word that immediately grabs attention.
In this song, the artist uses yonqui metaphorically to express an intense, almost addictive desire for his lover. He compares himself to Amy Winehouse, known for her struggles with addiction, to emphasize the overwhelming nature of his infatuation, making it a memorable and impactful choice.
Sabino's song "Milhouse" is a super fun and intense declaration of love, comparing the feeling to an addiction. He says that trying his lover's lips was like trying a drug for the first time, altering his reality. He even calls himself her "yonqui" [junkie], like Amy Winehouse, and says he'd "vender el alma" [sell his soul] like Milhouse from The Simpsons!
He's totally hooked, describing her kisses as smoke that takes him to the sky and her mouth as sweet as candy. He feels like she brought him luck, and now he only has eyes for her, saying "Todo estaba a oscuras y me diste luz" [Everything was dark and you gave me light]. He's got such a huge craving for her, a "tremendo antojo" [tremendous craving], that he jokes Walter White would want to traffic her, and Netflix would make a series about her! It's clear he's completely smitten and wants the whole world to know she's his "dama" [lady] and he's her "vato" [guy].
