Pariguayo is a Dominican slang term that can refer to someone who is a 'party pooper' or, more broadly, a naive or inexperienced person who is easily fooled or taken advantage of.
In the context of this song, it's used to contrast with 'tiguere' (a street-smart, tough person), implying that 'pariguayos' are those who are not savvy enough to navigate the street life and will have to pay their dues. It's an interesting word because it's specific to Dominican Spanish and carries a strong cultural connotation of someone who is out of their depth.
Kiry Curu's "LE DIMOS BALA" throws you right into the middle of a street-level conflict, fueled by loyalty and revenge. The song kicks off with a declaration of power and readiness to spend big, saying, "Vamos a despegar los block y los contenes / Vamos a hacer que entren los retenes / Vamos a demostrar quien la tiene / Y después vamos a gastar aunque sea doscientos pares de cienes" [We're going to take off the blocks and containers / We're going to make the checkpoints come in / We're going to show who has it / And then we're going to spend at least two hundred pairs of hundreds].
The central theme revolves around a tragic event: a friend was killed, and the crew is out for blood. Kiry Curu repeatedly states, "Me le dieron al loco en la parada / Y me le dieron una muerte equivocada / Pero al que lo vendió, lo agarramos y le dimos balas" [They got the crazy one at the stop / And they gave him the wrong death / But the one who sold him out, we caught him and gave him bullets]. This act of vengeance sets the tone for the entire track, as the artist and his crew are ready for anyone who crosses them, even if it means a shootout. It's a raw look at street justice and the intense bonds within a neighborhood.
