Jangueando is a very common slang term in Puerto Rico and other Caribbean countries, meaning "hanging out" or "partying." It comes from the English phrase "hanging out."
In the song, the line "Tú y yo jangueando en el Aventador" (You and I hanging out in the Aventador) paints a picture of a luxurious and carefree night out. It's an interesting word because it's a Spanglish term that has been fully adopted into the Spanish urban lexicon, making it a fun and relevant word for learners interested in modern Spanish slang.
The title is the word the chorus cannot stop repeating, worn down to two letters: toda collapses into toa, and the whole song is that one demand — all of you, all of it, tonight. FloyyMenor opens by fencing off what he wants before he says anything else: “Nena, no te voy a compartir, y si me toca ir / Te voy a hacer venir” (Baby, I'm not going to share you, and if I have to go, I'm going to make you come). When Cris MJ takes it over, the night gets counted in props — “Tú y yo jangueando en el Aventador” (You and me hanging out in the Aventador) — with the same flat appetite the song brings to everything else.
What gives it a shape is how carefully it refuses the other word. “Que te chingue no es que te amo” (Screwing you doesn't mean I love you) gets said twice, and the warning comes back plainer: “No te quemes, no quiero drama” (Don't get burned, I don't want drama), “Ni que me ames” (or for you to love me). The one image it allows to be mutual is “Tú eres diabla, yo tu diablo” (You're a devil, I'm your devil) — and it is followed immediately by “No me digas más 'te amo'” (Don't tell me 'I love you' anymore). Everything is on offer except the one sentence the other person might want to say.
