[2] Paquita started her career in Mexico City in 1970, where she performed at a local restaurant in Colonia Guerrero, and fans began returning every week to listen to her sing.

[3] Paquita’s catalogue of songs usually take a feminist stance against Mexico's sexist and “macho” male culture and attitudes, often pointing the finger at the men in her lyrics for causing problems in relationships, and generally making them out to be “tontos y bobos” (clowns and fools).

Paquita is known for her somewhat condescending way of speaking, and for her confrontational presence; her signature phrase, with which she often teases male spectators at her shows, is "¿Me estás oyendo, inútil?

In the 2021 Billboard Music Awards, when reguetonero and singer Bad Bunny went to the stage—to kindly help her with her faulty microphone—she (lovingly) told him “Eres un inútil”.

"[6] Her best-known song is "Rata de dos patas" (English: "Two-legged rat"), in which she compares an ex-lover to a variety of vermin and other untrustworthy animals, including bugs and “goddamn cockroaches”.

Paquita participated in the multi-artist 2010 Haiti earthquake benefit, lending her vocals to "Somos El Mundo"—the Spanish version of “We Are The World”, produced and organized by Emilio Estefan.

"[16] She then apologized to the LGBT community and did a special performance and a press conference in a gay club called Spartacus Disco.
