Meaning: Ready for battle

If you want baby to be the epitome of cool, give a thumbs up to Fonz. This masculine name derives from the Spanish, Italian, and Portuguese name Alfonso and means "ready for battle." Alfonso can be traced back to the 8th-century King of Asturias and became popular among kings and royal Spaniards. Baby will surely add to its legacy of strength and leadership. And there's no one you'd rather have on your side during battle than Arthur "The Fonz" Fonzarelli! This star of the retro sitcom Happy Days was cool personified with his leather jacket, so why not say "aaay" to this epic name?
