look up any word, like donkey punch:
Someone who is shit at lying
John's version of event's was totally unbelievable, he is such a poonocchio

A person who has told a lie and the resulting punishment inflicted by the peers of the liar involves someones butthole being placed upon the nose leaving a scent and/or evidence labeling them as being dishonest. Best accomplished when the perp is asleep.
That story he told at the party was such bs, after he passed out we poonocchioed him.
