Pachuco refers to a subculture of Chicanos and Mexican-Americans, associated with zoot suits, street gangs, nightlife, and flamboyant public behavior.
Pachuca is the female counterpart, often idealized as a beautiful Chicana woman in extravagant evening dress or a female version of the zoot suit, out with a pachuco boyfriend for a night on the town. Pachucas broke taboos of their time by wearing men's-style pants sometimes and appearing in public often with their pachuco boyfriends; at the time, a "good woman" was considered to have her place in the home.
Pachucos became known for their distinguished look, dialogue, and actions. Pachucos dressed in recognizable Zoot suits, and often styled their hair into ducktails. Things like decorative chains and tattoos were also sometimes part of the pachuco look. The unique speech of pachucos was a very important element of their defined style. Consisting of creative phrases and some English words, Caló (Chicano) was a very popular form of speech among pachucos.
