Guido is a given name. It originated in Medieval Italy. Guido later became a male first name in Austria, Germany, the Low Countries, Spain, Portugal 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 name "Guido" has developed as a term used in American culture as a stereotype and ethnic slur for working-class urban Italian Americans.
"Losing" loses, God wins, Guidos Love, and you must stop slurring "your" guides. Please do not be wounded in any puerile way!
