Guachupino Goo-ah-shoe-pee-noh, sometimes spelled as Wachupino is a slur almost exclusively used by spaniards to refer to:
1. South
American people.
2. Any
south american dialects, variations of the Spanish language in south America or Latin American dubs.
In a really weird way, this word is not often used as a direct insult but as a
derogatory term used in conversations between Spaniards, that is why most south Americans outside spain are not familiar with it.
