poongry

A state of red-faced anger resulting from trying very hard to poop, most common in newborns.

An amalgum of pooping and angry invented to describe the frequently observed squealing and grunting of newborns while they learn to defecate.

Dad: "Why's the baby so upset right now?"
Mom: "He's just poongry. He'll soon be happy but need a change... hopefully it's not a diaper blowout!"
