Giles is an Argentinian slang term that translates to "idiots" or "suckers." It's a very common word in Argentinian Spanish, but less so in other Spanish-speaking countries, making it interesting for learners.
In the song, the phrase "Dormir es para giles" (Sleeping is for suckers/idiots) sets the tone for the artist's relentless work ethic and ambition. It implies that only those who are foolish or lazy would waste time sleeping instead of pursuing their goals.
YSY A's "DORMIR ES PARA GILES" is all about that grind, that hustle, and the idea that sleeping is for suckers! He's basically saying if you're not out there making moves, you might as well stay in bed. The title itself, "Dormir es para giles" [Sleeping is for fools], sets the tone, but he quickly adds a twist: "más de gil es / Estar despierto viendo todo el tiempo que perdés" [it's even more foolish / To be awake watching all the time you lose]. It's a blunt call to action!
He's living proof of this mentality, claiming he doesn't even know how to sleep because he's so busy. YSY A flexes about his success, from his growing shoe size to building an empire at 23. He's confident in his rhymes, comparing them to attractive women who also become friends. This track is a high-energy declaration of ambition, a warning against wasting time, and a celebration of constant effort. He's not just talking the talk; he's walking the walk, and he's definitely not recommending sleep to his crew!
