An affectionate term that loving daughters give to scary fathers. A Popi is a very lovable pops that is also monumentally scary when angered. A Popi usually has a square head like a television, no neck and occasionally sports a goatee or an Italian gangster hairdo. Avoid being smacked by a Popi because it frequently creates concussions.
He hasn't met my Popi yet because he still has his shoes and no shoe shaped scar on his forehead.
