“Me Porto Bonito” (I behave nicely) is a flirt from Un Verano Sin Ti (2022). Chencho Corleone and Bad Bunny tell a woman who knows she's beautiful — and is newly confident — that for her, they'd behave; they'd do things right. It's playful, a bit cheeky, and one of the most-streamed songs of that summer.
The chorus, sung by Chencho, is slow and catchy; Bad Bunny's verse is quicker and full of Puerto Rican slang and English loans. That contrast makes it a good bridge song: start with the chorus, then work up to the verse.
“Portarse bien/bonito” is everyday Spanish for “to behave”: parents say it to kids, and lovers to each other. Listen for the dropped “d” in words like “cansao” and the Caribbean “r” that drifts toward “l”.
