Hecho cuadritos literally translates to "made into little squares". This colorful idiom is a very expressive way to say you're smitten, head-over-heels, or completely crazy about someone.
In the song, the line "¿Cómo te explico? Me tienes hecho cuadritos" (How do I explain it? You have me smitten) captures the feeling of being totally captivated and overwhelmed by love. It's a memorable phrase that paints a vivid picture of being completely disarmed by another person's charm.
Have you ever tried to play it cool with someone, only to fall head over heels the minute they kiss you? That is exactly what Becky G and Manuel Turizo are dealing with in "QUE HACES". Becky opens by admitting she would deny having feelings if anyone asked, but she is already feeling jealous ("sintiendo celitos por ti" [feeling a little jealous over you]) and thanking whoever taught him how to kiss. She calls herself "la que no quería querer" [the one who didn't want to fall in love], yet here she is, counting down the days until they meet up again.
The chorus hits with an insanely bold, funny proposition: "Dime qué haces este viernes y el resto de tu vida" [Tell me what you are doing this Friday and the rest of your life]. They throw out all the options at once: "¿Nos vemos o qué? ¿Nos casamos o qué? ¿O nos comemos y que el tiempo decida?" [Are we seeing each other or what? Are we getting married or what? Or do we hook up and let time decide?]. Manuel matches her direct energy with Colombian slang, asking to "parchemos dándonos piquitos" (where parchar means to hang out or chill, and piquitos are little pecks or kisses) and admitting she has him "hecho cuadritos" [turned into pieces / totally hooked]. It is a delightfully impatient pop track about throwing caution out the window when the chemistry is simply too good to ignore.
