Gabacho (Spanish pronunciation: [ɡaˈβatʃo]; feminine, gabacha) is a word used in the Spanish language to describe foreigners of different origins.
In Spain it is used as a pejorative reference to someone French, coming from the Catalan word gavatx which translates as foreigner.
In Mexico, gabacho refers to Anglo people of non-Latino decent. Sugar cane leftovers after chewing (usually spit out garbage) and usually white.
In the United States, the word is a pejorative term used mainly by Chicanos (and by extension, American Hispanics) for White Americans. It is not widely used or understood by Spanish-speakers in the Americas outside of the USA and Mexico. The term güero is sometimes used interchangeably to describe someone who is pale skinned.
