Jaque mate is the Spanish term for "checkmate", the game-ending move in chess.
In this song, Rauw Alejandro uses it as a clever metaphor for a game of seduction. He sings, "Le di tabla, me dio jaque mate" (I gave her the board, she gave me checkmate), suggesting he thought he was in control of their encounter. However, she made a move so powerful that she 'won' the game, completely captivating him with her response.
Rauw Alejandro kicks off this track by trying to arrange a secret meeting. He's direct and ready to go, telling a woman, "Solo tienes que indicar / La hora, que el lugar yo lo tengo" (You just have to say / the time, 'cause I have the place). It turns out, this whole plan was sparked by a social media post. He saw her Instagram story for her "Close Friends" and took it as a sign: "Vi que estabas sola y que querías bellaquear y prender" (I saw you were alone and wanted to get freaky and turn up). His goal is simple: "Vamos a recordar los tiempos del motel" (Let's remember the motel times).
He feels they have unfinished business, calling it "algo pending" (something pending), and suggests a casual hookup, which he calls a "polvo friendly" (a friendly f*ck). The song then gets more specific, describing their intense chemistry with a clever mix of cultures: "Y si nos juntamos, somos cafeína con mate" (And if we get together, we're caffeine with mate), blending his Puerto Rican coffee with Bizarrap's Argentinian mate tea. The lyrics are full of explicit details about their encounters, from the back of a Bentley to a private location that "no lo tiene Google Maps" (Google Maps doesn't have).
