(Noun) a character in the world of penis puppetry. The hungry sparrow can only be created from an uncircumcised penis. The puppeteer grabs the very tip of the uncircumcised penis separating the flaps of foreskin thereby creating an opening, whilst pulling the penis directly upward. The result is the appearance of a hungry sparrow yearning sky ward, looking for his Mom and the promise of food. A puppeteer with advanced skills can manipulate the foreskin in a manner that when combined with bird calls truly brings the hungry sparrow to life.
When he gets drunk he runs around the party showing everyone his hungry sparrow. It is just not cool.
