I was in Nicaragua and I heard white people referenced as chille's. is that the correct spelling?
Hey chille, lets go.
Chele (from leche) is a white person
The apparent cleverness of this term is found in the fact that the syllables of le-che are reversed to make che-le. Somebody in Nicaragua must have thought that they were funny, as the implications behind this term is obvious: milk is white and so are most foreigners.
I've just recently heard a petite, white friend of mine referred to as "chelita" (little chele) by someone from El Salvador so it's not just a Nicaraguan thing but it's definitely regional. I've never heard a Mexican say this and a Gautamalan was confused by the term because "chelita" would mean "little beer" (from slang chela) to him. They would say "gringo" or "gabacho" or maybe "güero" (blond).
Guatemalans also use the term canche to refer to a "white" person.
