1º_ Variant of pifano ("piccolo, and its interpreter in a military band") . 2º_ Child orphaned by parents, in particular if they died in a war. The accepted origin is that it comes from the previous etymology, because these boys were cared for by the army and in military bands they used to play the pifano. But another interesting origin circulates on the web, also from German, such as pimpf ("spoiled, unruly, rascal child") that was used during World War II in Hitler Youth camps to call children from 6 to 10 years old, orphaned or evacuated from cities under Allied bombing. Being the Spanish army admirer of the German, he took many German words among which could be this one that became the affectionate 'pinfanito' and then in a regression as 'pinnfano'. See english/brat . 3º_ It is a popular way of calling the long-legged mosquito or mosquito. 4º_ By the previous one, it is said familiarly to the person very tall, with long legs.
