Cucarme is a fun, slang verb that means "to tease me" or "to provoke me", often in a playful or flirty way. It's a great example of Puerto Rican slang that you won't find in a standard textbook.
In the song, Young Miko sings, "Siempre te pierdes solo para cucarme" (You always disappear just to tease me). She's describing a playful cat-and-mouse dynamic where her love interest acts distant just to get a reaction out of her, making it a key word to understanding their relationship.
Puerto Rican rapper Young Miko brings pure confident flirtation in "Princess Peach," revolving around a girl who loves playing hard to get. The girl leaves Miko on read, goes quiet on social media, and disappears on purpose just to provoke her—"Siempre te pierdes solo para cucarme" (You always disappear just to tease/provoke me). But Miko cannot stay mad. She gives a playful nod to video games by calling her girl's curves a "peach" (referencing Nintendo's Princess Peach while using the peach as slang for a great backside), shrugging off the mixed signals with "Con ese peach, mami, ¿Quién se enoja contigo?" (With that peach, mami, who gets mad at you?).
The track is packed with smooth late-night flexes and pop culture drops. Miko hypes up her crush as a "savage, Fenty" (referencing Rihanna's lingerie line, Savage X Fenty) and teases her for thirst-trapping on Instagram: "Otra vez en el close friends / Apareció sin sostén" (Once again on the Close Friends story / She popped up braless). She backs up her charm by offering unlimited perks, telling her "Llévate la Black Card, que no hay pin" (Take the Black Card, there is no PIN) and telling her to call her anytime on the "hotline bling" (shouting out Drake's famous song). It is a witty, laid-back Latin Urbano anthem about letting someone push your buttons simply because you are too hooked on them to care.
