A friendly way of saying someone is a moron. Can be best applied to British or Australian people, as they have very ugly accents. As well as bald headed people.
"Shit man.... did you see that asshole cut me off? What a pongo."
A Pongo is the bestest boy dog around. A pongo will be your life long friend who will take up all of the free space in your heart. A house isn’t a home without a golden retriever called pongo.
Dominic and Amy took Pongo for a walk at the park.
