The Mexican slang address “Güey” or "guey" always, with a smirk, means “
cuckold,” which is the only word in English that labels the man whose
woman cheats on him. In Mexican Spanish, a man’s unfaithful wife or girlfriend causes horns to grow upon his head, which only he cannot see. There the
word connects with “Buey” or oxen, and serves as the root for the
popular song “El Venado” about a man who grows horns. The
word comes loaded with sexuality, always disparages, and always signifies low class aliterate personalities, and should always insult (as does the use of “
Bitch” or “Niggar” in English) as a label. In Mexican Spanish, in direct opposition to the Mexican “Chingón” which signifies a heroic fornicator, or a type A personality, the overuse of the label “Guey” among the lower classes seeks to replicate the good-old-boys comraderie of the Mal Hablados, or potty mouths, of the ruling class.
Oye, Güey, dime que no supieste
nada, pero
nada, de que este guey utiliza tu mujer como todo
la vecindad, guey.
