Horneado literally means "baked," as in fresh from the oven. In this song, it's clever slang for being completely head-over-heels or "high" on love.
The singer says, "Me tienes horneado, todo loco" ("You have me baked, totally crazy"), perfectly capturing that dizzying, all-consuming feeling of a new crush. It's a fun, modern expression you'll hear in regional Mexican music!
This song is a straight-up declaration of intense desire. Los Gemelos De Sinaloa are not playing around here; the singer is completely obsessed with someone and can't wait to see them tonight. He tells her, "Me tiene loco por mirarte esta noche" (You have me crazy to see you tonight) and that he's coming to get her in five minutes, so she better get ready.
The whole song compares this feeling of love and lust to an addiction. He says it plainly: "Amor, tu cuerpo es mi droga y sabes" (Love, your body is my drug and you know it). He feels dazed and crazy, saying "Me tienes horneado, todo loco, ondeado" (You have me baked, all crazy, wavy). It's a powerful and direct way to describe a feeling that's so overwhelming he needs it like he needs air to breathe.
