The description of something or someone being penguin-like.
1. Dude, this guy walks like a penguin.
2. Kyle: It's fucking freezing out here! Aren't you even cold?
Jer: It's okay, I'm like a penguin, I'm used to this sort of thing.
3. Claire, I think I'm going to write a book. It'll be the "Book of Penguinisms". Everything penguin, from the cute birds themselves, to the quirks about the people we hang around with.
