Algarete is a Puerto Rican slang term that means "wild," "out of control," or "crazy." It's a vibrant and energetic word that perfectly captures the party atmosphere of the song.
Natti Natasha uses it to describe a night where she and her friends are letting loose and having an unrestrained good time. It's a word that immediately sets the tone for a night of fun and freedom, making it very enticing for a learner.
"Algarete" is Puerto Rican slang for off the rails, and Natti Natasha uses it as a status report on one specific night. She opens by admitting this is out of character — "Ya casi ni salgo pero es que esta noche nos fuimos algarete" (I hardly go out anymore, but tonight we went totally wild) — and then spends the rest of the song describing the night instead of apologising for it. The details do the work: the car outside, "El maquinón parqueao' afuera al lado del tuyo lo hace ver como un juguete" (the big car parked outside next to yours makes it look like a toy), the club at capacity, and a man across the room who keeps looking.
What holds it together is how she prices herself. "El sabe que salgo cara, no tranzo por migajas" (he knows I come expensive, I don't settle for crumbs) is the line the whole song leans on, and when she asks "¿Que hay una mejor que yo? No estoy segura" (that there's one better than me? I'm not sure) it lands as arithmetic rather than doubt. The chorus keeps circling the same three facts — the night is right, the club is packed, and he is watching — and by the last verse she is repeating the opening line, still unbothered.
