The langage of the Mexican youth in the 60’s
The young borrowed their language not only to the popular speech of Mexico, the one of the gangsters and of the hot neighbourhoods, but also to the "Spanglish", the Spanish spoken in the northern border of Mexique. This new way of speaking created new words made from American slang and by giving new significations or new grammatical forms to pre-existing words. It invented many puns often of a sexual nature. This transgressive form of speech, sometimes scurrilous was of course considered vulgar by people who did not belong to this bohemian culture. It was claimed by the young people themselves as a sign of differentiation and of belonging to a group.
