Avionetica is a diminutive of avion (plane), meaning "small plane" or "little plane." It's a less common word in everyday Spanish, making it stand out in the lyrics.
In the song, the artist expresses a desire for "una avionetica pa' mover todas la semana" (a small plane to move [product] every week). This line hints at a lifestyle associated with illicit activities, where a small plane would be used for transporting goods, adding a layer of intrigue and context to the word's usage.
"Percocet" is Alex Rose's confession that heartbreak turned into a habit. He opens plain: "Dime por qué me ignoras" (Tell me why you ignore me), then names the fix he reached for: "Me tienes metiéndome percocet" (You got me popping Percocet). A few lines later he counts the pills out loud: "Con tus percocet, de tres en tres ya me he metido doce" (With your Percocet, three by three I've already taken twelve).
The remix stacks on guest verses that trade the ache for swagger, codeine, Adderall, and a line about being "loco como el Joker" (crazy like the Joker) with her cast as his Harley Quinn. There's a run of imported women and champagne that plays more like a brag list than a story, but the hook still drags it back to the same wound: it just wants one person to pick up the phone. By the time the song fades out on producer tags and ad-libs, the last real line he sings is "Me estoy volviendo loco por ti" (I'm going crazy for you), and the whole track was never really about the pills.
