Boliguayan () a generally derogatory expression used in Argentina to refer to Bolivian and Paraguayan immigrants, whose descendants born in the country are among the most numerous, Peruvians are generally also included. Although it is not completely accurate, there are versions that indicate that the term emerged in the 1990s when immigration from neighboring countries increased. The vast majority are mestizo or indigenous originating from these countries, this contrasts greatly with the more criollo and castizo light-skinned phenotype of Argentina. This term is similar to that of Brasiguayos, which is used for descendants of White Brazilians in Paraguay. Etymology and uses. It is a grammatical contraction of the Bolivian and Paraguayan demonyms. The expression is frequently used to disparage migrants whose origin comes from the aforementioned countries, which is why it is considered a pejorative term. It is also generally used to refer to Peruvian immigrants and their descendants, given that they share certain characteristics with people born in those states bordering Argentina. Demographics.
