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.
