Luis de Alba

Created sometime in the 1970s, the character is a very rich young man with a haircut similar to that used by the Beatles in their early years and depicts sarcastically and exaggeratedly the stereotype of a so-called "fresa". He enjoys deprecating low- to middle-class people with illusions of grandeur, airs of importance, bad taste, and colorful (low class) slang, while at the same time emphasizing his own importance and class-superiority, using a lot of "high class" slang. The people he deprecates are pejoratively called nacos. Pirrurris refined the ridicule of nacos into nacology, the study of the naco. Sitting behind a desk, he would explain the naco to his audience in scientific terms.

So viewers would not take his remarks seriously, the character's locution and mannerisms are a parody of the so-called juniors, the pompous young sons of upper-class Mexicans, known for their tendency to dismiss anyone else as a naco. He frequently refers to his millionaire Papi and expresses amazement at the most mundane problems faced by normal people. Incredibly narcissistic, he explains that his name comes from the mathematical constant Pi and rorro (slang for handsome), in that he is "3.1416 times handsome".

Pirrurris has become a common Mexican epithet for someone who looks down on others, is a materialist and superficial but however non-intelligent and air-headed (although not aware of this), and act as if one were above one's real economic station. Mexican leftist politician Andrés Manuel López Obrador has used the term on different occasions to refer to his right-wing political opponents.

Luis de Alba started his artistic life when he was a child playing a character named "Solin". Solin was the always companion of a supposed man with gifted powers (Kaliman). Kaliman was the name of a daytime radio drama transmitted to his audience exclusively by radio in the 1950s, 1960s, 1970s, and 1980s.
