Bellaco is a Spanish slang term that can mean 'naughty', 'mischievous', or 'sly', often with a connotation of being a bit of a scoundrel or a player, especially in a romantic or sexual context.
In this song, the artist uses it to describe himself: "pero yo soy un bellaco y todavía te sigo" (but I'm a bellaco and I still follow you). It implies he's persistent and perhaps a bit cunning in his pursuit, even after being left behind. It's an interesting word because it's not commonly found in everyday Spanish lessons but is very present in urban music, offering a glimpse into more colloquial and regional expressions.
In "De Lejitos", Puerto Rican singer Jay Wheeler admits that bad timing completely ruined a fling. He admits he was already seeing someone else while hooking up with her ("yo tenía baby" [I had a girl]), and she understandably got furious when she found out. He sings "te encojonaste, no te gusta ser la segunda opción" [you got pissed off, you don't like being the second option]. After getting ignored ("te piché la última ve'" [I ignored you last time]), she walked away, found a new man ("tienes otro gato" [you have another dude]), and cut contact entirely.
Now she keeps her distance ("estás de lejitos"), but he refuses to let it go. Jay Wheeler drops zero romantic pretenses here. Instead of apologizing nicely, he begs for another late-night hookup, admits he stalks her profile even though she unfollowed him, and even offers to be her side piece ("a mí no me molesta ser tu chillo" [I don't mind being your side dude]). Puerto Rican slang runs heavy throughout the track: he talks about grinding denim on the dance floor ("guayarte el mahón en la disco") and reminisces about a birthday hookup that can never be topped ("el polvo el día de mi cumple nunca se supera"). It is petty, blunt, and wildly direct about wanting someone back purely out of lust, even while knowing he messed it up first.
