Aprieta literally translates to 'squeezes' or 'tightens', but it carries a fierce double meaning in urban slang. It is frequently used to describe someone who is stepping up their game, looking incredibly good, or raising their personal standards.
By singing "la baby ahora aprieta", KAROL G perfectly describes a newly single woman who has leveled up and will no longer tolerate being lied to.
This song is a total anthem for anyone who's just gotten out of a bad relationship and is ready to feel amazing again. KAROL G and Young Miko paint a picture of a woman who has been set free. The song asks, "¿Qué le habrán hecho a esa bebé que está rebela'?" (What did they do to that baby that she's rebellious now?). The answer seems to be that she broke up with her boyfriend, maybe because he was an "infiel" (cheater).
Now, she's hitting the club to have a good time. She's confident, independent, and makes her own money. The most important line is the chorus: "Ahora está dispo', pero no cualquiera le da" (Now she's available, but not just anyone can get with her). She's not crying over some idiot, because as Young Miko reminds her, "Tú eres bichota y por pendejo' no se llora" (You're a boss and you don't cry over fools). This is all about knowing your worth and having the best time after leaving someone who didn't deserve you.
