Aprovéchala is a command, meaning "take advantage of it" or "seize it." It's a dynamic and action-oriented word that stands out in the lyrics.
In the song, Becky G sings, "Solo una oportunidad, aprovéchala" (Only one chance, take advantage of it). This phrase is a direct invitation, urging the listener to seize the moment and make the most of the opportunity presented, adding an exciting and urgent tone to the song.
An oasis is water you can see and might not reach, and Becky G picks the word on purpose. She opens by turning down the obvious role: "No quiero ser tu amor" (I don't want to be your love), then "Hay humo en mi reflejo" (There is smoke in my reflection). The plan follows, stated flatly: "Robo tu corazón / Luego desaparezco" (I steal your heart / Then I disappear). So the chorus is the offer and the catch in one breath, "Quiero ser tu oasis" (I want to be your oasis), because an oasis is somewhere you arrive at, drink, and leave. She sets a deadline too: "Solo una oportunidad" (Just one chance), "Aprovéchala" (Make the most of it).
Halfway through, the song switches to English and drops the mirage entirely. The Spanish half flirts; the English half reads like receipts. "Rich friends asking about it" and "Took me to Italy gave her the boot" are not images about thirst, they are a list of things that happened, and the bragging gets specific enough to be funny. It is a bit much, and it knows it. By the last chorus "Por ti me muevo así" (For you I move like this) lands less as a promise than as a demonstration.
