Pocho (feminine: pocha) is slang in Spanish used in Mexico to refer to Mexican Americans and Mexican emigrants.^[1][2] It is often used pejoratively to describe a person of Mexican ancestry who lacks fluency in Spanish and knowledge of Mexican culture.^[3] It derives from the Spanish word pocho, used to describe fruit that has become rotten or discolored.^[4]

The term can refer to the following:

• A Mexican American or expat who speaks broken or no Spanish.
• A Mexican American who speaks Anglicized Spanish, colloquially known as Spanglish.^[5]
• A Mexican that has emigrated from Mexico and settled or naturalized in another country.
• A Mexican that travels, works, or lives outside of Mexico for an extended period of time. e.g. Mexican students studying abroad.
• A Mexican that does not adhere to traditional Mexican culture, customs, and etiquette.
• A nickname in Argentina (Pocho or Pocha). For example, the popular Argentine president Juan Perón was called "El Pocho" as well as the Argentinian football players Ezequiel Lavezzi and Federico Insúa.
• A 1959 Chicano novel by José Antonio Villarreal.

Pochos are usually identified by their use of non-standard Spanish. Code-switching—and the use of loanwords—is common, as in many languages; however, it is the overall use of words and phrases popular in English-language/American culture translated into Spanish, sometimes quite literally, that may earn one the label of “pocho/a” from others. Code-switching often involves inserting English prepositions or objective nouns, such as saying "Voy a ir shopping ahora en el supermarket", or “I am going shopping now at the supermarket”.

Modified loanwords are referred to as "pochismos", and will usually sound quite similar to their English-language counterpart. Examples include:

• mopear instead of trapear (to mop)
• troque or troca instead of camion (truck)
• parquear instead of estacionar (to park)
• chequear or checar instead of mirar, revisar or verificar (to look, to check/inspect, or to verify)
• noquear instead of derribar (knock-down, or knock-over, for example in boxing when a boxer knocks out an opponent)
• rapear (to rap), instead of rimar (to rhyme)

A clear example of a popular American phrase that has been adopted, by people familiar with both cultures, would be Clint Eastwood's famous quote, “Make my day”, which has been increasingly used in Spanish as "Hacer mi día."

Pocho is also a Hawaiian Pidgin English slang term used to describe an individual of Portuguese descent.^[6]
