Guido is a given name Latinised from the Old High German name Wido. It originated in Medieval Italy. Guido later became a male first name in Austria, Germany, the Low Countries, Scandinavia, Spain, Portugal, Latin America and Switzerland. The meaning of the name is debated, with various sources indicating the Germanic "Wido" means "wood" and others connecting the Italian form "Guido" to the latinate root for "guide".The slang term Guido is used in American culture to refer derogatorily to an urban working-class Italian or Italian-American male who is overly aggressive or macho with a tendency for certain conspicuous behavior. It may also be used as a more general ethnic slur for working-class urban Italian Americans.
