"Mongrel complex", or alternatively "Mutt complex", is an expression used to refer to a collective inferiority complex reportedly felt by many Brazilians when comparing Brazil and its culture to other parts of the world, primarily the developed world, as the reference to a "mongrel" carries negative connotations attributed by Brazilians to the racist perception of most Brazilians being racially mixed as well as lacking in desirable cultural refinement.
