Escarmiento is a powerful noun for a lesson learned through a harsh or painful experience, almost like a punishment. It's not a word you hear every day, making it a great one to learn.
In the song, Bryant Myers reflects on his mistakes, singing "perderte me sirvió de escarmiento" (losing you served as my painful lesson). He uses this word to express the profound and bitter regret he feels, acknowledging that losing his love was the harsh consequence he needed to finally learn his lesson.
This song is called "Triste," which means "Sad," and it absolutely lives up to its name. Bryant Myers and Bad Bunny are walking through the ruins of a relationship they broke themselves, and they are not handling it well. The whole track is a confession of regret. Myers admits he lied, cheated, and broke every promise he made, including making her his wife. He knows he's the reason she lost faith in love, saying, "yo mismo jodí los pétalos de la rosa" (I myself messed up the rose petals).
The song is full of specific, painful memories. He remembers their intimate moments in his BMW M3 and messing around in the park on skates. Now, he's just walking alone through San Juan, smoking to deal with his depression, and failing his classes because he can't concentrate. He's tortured by the thought of her with someone else, repeating, "Triste, mami me siento triste" (Sad, baby, I feel sad). It's a blunt and honest look at someone who messed up badly and is now living with the consequences.
