The Spanish word pucho evolved in Bierzo, a sub-region of Castile and Leon. Normally used as slang for "buddy", has also loosely been used as a descriptor for a smaller, lesser person by adding the suffix "-ito". From the Spanish, puchito has also recently taken hold in the United States as slang. This can be accredited to Julio Nieves (PR) who is thought to be the first known true "puchito" in the United States.
