"Gachupín" is a derogatory name that is applied in Mexico and
Central America to Spaniards. There was also formerly the "cachopín" form, now unused. In other parts of Latin America, cachupín is used, with the same meaning.
Gachupín is an eponym derived from a northern Spanish hidalgo surname : the Cachopines , from Laredo , currently Cantabria , and popularized in the golden centuries as a stereotype and literary figure
representing the hidalgos, a relatively high
social class caricatured as arrogant. The cachopín , guachapín , cachupín and cachupino forms are also registered.
