I have heard some people describe this as just any upper class person. However, are there certain things like brands, car, names, neighborhood that define “what does it mean to be a tincho”
Funny you heard about the term “tincho”. It’s the nickname used for people named “Martin”, which is believed to be a typical name among people of upper class (more commonly known as “chetos”). So “tincho” became synonym of “cheto” or upper class.
Here in Argentina the definition of “chetos” varies. There are different types of chetos: new rich, old money, from Buenos Aires, from the provinces, from the countryside, etc.
The typical old money cheto wears classical clothing, doesn’t show off, studies at a good public university like University of Buenos Aires or the most expensive private universities like UdeSA or Di Tella and lives in a traditionally rich neighborhood. A lot of old money chetos own vast extensions of farmlands and a home in the countryside. They have a traditional surname (from the colonial period), usually two Spanish surnames.
The typical new rich cheto lives in a gated community, dresses according to the latest trends, wears fashion brands, goes to private universities like UADE, likes to show off and has a normal surname (not from the colonial period), usually Italian.
