Fierrosqui is a colloquial and somewhat playful term for "firearms" or "guns." It's a diminutive of "fierro," which literally means "iron" but is often used as slang for a weapon.
In the context of this song, which touches on themes of street life and a certain lifestyle, the word adds a layer of authenticity and a hint of danger without being overly aggressive. It's a unique and memorable piece of slang that stands out.
"RIKI" is a breezy, joke-filled regional Mexican track where Neton Vega brags about not taking love too seriously. The hook leans on playful slang, saying he's not worried as long as things stay easy and fun ("riqui").
The verses lean into swagger: a new car, easy confidence with women, loyalty to his crew, and zero interest in getting attached after a breakup. He'd rather move on than dwell on anything, and near the end he jokes about women from a few different countries, keeping the whole song light rather than sincere.
It's less a love song than a shrug: a fun, slang-heavy brag track about staying carefree.
