Pagophaggot
A nasty name for someone who can't stop crunching ice like it's their last meal and they're dying of hunger.
My dog has Pagophaggot. He chews ice like it's a bone and he's a wolf.
She's got Pagophaggot. I saw her eat an entire bag of ice cubes at 3 a. m.
He’s a Pagophaggot. I’ve seen him chew ice so hard his face turns blue.
