Sarfarosh/ Sarfaroshi Meaning

Well, Sarfarosh doesn't exactly mean Daredevil, though it implies that many times. Sarfarosh is made of Sar and Farosh, sar is head while farosh is a seller, so sarfarosh would literally mean a head seller, though the word actually is used such that giving it a better meaning, that is a person with fervor, or high enthusiasm for doing something. The feeling itself is called Sarfaroshi.
