What does bimbi mean?

The meaning of "Bimbi in Gamba" is literally translated into English : Kids on Legs (just as cattle are called on hoof). The meaning of "Bimbi in Gamba" in the daily spoken Italian language is "Clever Kids," somebody who is said to be "in gamba" is meant as someone who is clever (as in intelligent, in the positive sense, not in the bad sense).

Alessandro Zanardi, the former Indy Champ (2x) and Formula One GP Professional driver (who still races cars in European Touring Car Championship division, and who is an amputee who lost 2 legs in a terrible race car crash at the Lausitzring in Germany) used the expression "in gamba" cleverly for his charity (named : Bimbi in Gamba) that helps with funds raised to aide children that have serious problems with their legs (including amputees).
