Agüita is a colloquial and somewhat playful term derived from "agua" (water), but in this context, it means "to get upset" or "to feel down."
It's a more informal and less common way to express sadness or annoyance than typical words. In the song, the singer boasts, "Y de todas, sé que ninguna se agüita" (And of all of them, I know none of them get upset), implying that despite his many romantic escapades, none of the women are truly bothered by his behavior. This makes it an interesting and unique word choice.
Get ready to meet "El Mil Amores" [The Thousand Loves], a character who definitely lives life to the fullest! Los Dos Carnales introduce us to a guy who's earned a bit of a reputation, saying "Me llené de mala fama, que estoy hecho pa' las damas" [I got a bad reputation, that I'm made for the ladies]. He's a self-proclaimed ladies' man, enjoying "tantas damas, tantas travesuras" [so many ladies, so many mischiefs] and isn't shy about it. He even jokes, "Lo viejero no se quita porque ni que fuera gripa" [Being a womanizer doesn't go away because it's not like it's the flu] – a pretty blunt way to say he's not changing for anyone!
But it's not all about the ladies. While he's out "cortando flores" [cutting flowers], he also values his friends, stating, "Y respeto siempre a los amigos" [And I always respect my friends]. He's all about enjoying the present, letting the past go, and toasting to "la noche y los placeres, por el vicio y las mujeres, y amistades que me quieren" [the night and pleasures, for vice and women, and friends who love me]. It's a fun, honest look at a guy who's just living his best life, even if it means being called "el mil amores" [the thousand loves]!
