Trolleys is an interesting word choice because it's an English loanword used in a Spanish rap song. While it literally refers to shopping carts or small wheeled vehicles, its inclusion here is likely a play on words or a reference to something specific within the artist's context.
In the lyrics, Cosculluela says, "Vayan alineando los trolleys," which could metaphorically mean
Cosculluela's "TSVK" is a track that feels like a declaration of dominance and a warning to his rivals. He's not holding back, making it clear that anyone who messes with him will regret it. He talks about past enemies being "drowned" ("Ahogaron pero todo futuros enemigos"), suggesting a history of overcoming challenges and asserting his power.
He's confident and unbothered, saying he remains "tranquilo" (calm) even as he talks about people trying to find him. There's a lot of imagery about being untouchable and always being one step ahead, like when he mentions people looking for him in the "funda" (case) or trying to "tumba" (take down) what he's built. It's a song that really embodies the swagger and self-assuredness of Cosculluela, letting everyone know he's at the top of his game.
