Estrella fugaz literally translates to "fleeting star", which is the beautiful Spanish phrase for a shooting star.
In this empowering song, Lele Pons uses the term metaphorically to describe a past lover who burned brightly but disappeared quickly from her life. It perfectly captures the essence of a short-lived romance and is a fantastic piece of poetic vocabulary to add to your Spanish toolkit.
This song is a fantastic anthem for anyone getting over a bad relationship. Lele Pons is telling someone off, making it clear she knows their love was just a "juego" (game). She's not falling for it anymore, singing, "Dices te quiero y no te creo" (You say 'I love you' and I don't believe you). The relationship was never the real deal, just something that made her suffer.
But here's the best part: the big reveal! Her ex thinks she's still stuck walking in their "veneno" (poison), but she hits back with an amazing image. She tells them, "Pero olvidas que no camino / Que yo he aprendido a volar" (But you forget that I don't walk / That I have learned to fly). She's not just walking away, she's soaring above all the drama. She's learned to fly on her own, and she's better for it.
