Enchochado is a colloquial and somewhat vulgar Spanish term, primarily used in Spain, that means to be completely infatuated or obsessed with someone. It's a very strong and informal way to express being head-over-heels.
In the song, Don Patricio repeatedly uses "aún sigo enchochado de ti" (I'm still obsessed with you) to convey a deep, almost uncontrollable longing and infatuation. This word is memorable because of its intensity and its unique, informal flavor, making it stand out from more common romantic expressions.
Don Patricio's "Enchochado De Ti" is a super honest look at being completely obsessed with someone, even when you know it might be a bit crazy. He admits, "Aunque no sepas mucho de mí / Disculpa estoy ahorrando pa' ti / Pa' comprarte la luna" [Even if you don't know much about me / Sorry, I'm saving for you / To buy you the moon], which is such a sweet, over-the-top way to say he's all in. He can't shake the feeling, saying "no se me quita el gusanillo de ti" [I can't get rid of this craving for you].
It's also a song about the struggle between holding on and letting go. He even tells her, "Mami corre, vete de aquí / Que esto es una locura" [Baby run, get out of here / Because this is crazy], like he knows it's intense but can't help himself. He'd rather pretend life isn't hard than deal with the uncertainty, confessing, "Es más fácil fingir / Que esta vida no es dura / Que seguir con la duda" [It's easier to pretend / That this life isn't hard / Than to continue with the doubt]. He's still waiting, still hoping, because he's just that "enchochado de ti" [obsessed with you].
