The lyrics of "Pachuco" by Maldita Vecindad Y Los Hijos Del Quinto Patio are sung in a questioning and almost mocking tone towards the youth of the present who dress in a way that deviates from the norm of past generations. The speaker cannot understand why anyone, particularly women, would dress in a punk or rock style rather than the traditional formal attire. The use of the term "greñudos" (meaning those with long, unkempt hair) shows the disapproval towards more relaxed and unconventional looks.

The repetition of the lines "Hey pa fuiste pachuco, también te regañaban" ("Hey dad, you were a pachuco too, people also scolded you") is significant, as it acknowledges the fact that in his youth, the speaker's father was also part of a youth subculture that was not accepted by society. This repetition serves to contrast the speaker's critical view of the present with his father's past experiences. The mention of being a "pachuco" refers to the Mexican-American subculture of the 1940s and 1950s, which was known for their extravagant style, dancing, and music. This suggests that despite societal disapproval, youth subcultures have existed throughout history.
