Define Walking Like A Penguin Meaning

Walking Like A Penguin
The walk, or waddle, one does as a huge shit is approaching which has come on without a solid release plan causing them to clinch they butt cheeks and seek the closest toilet for evacuation.

Luke sure had a rough day at school today. Poor kid was locked out of the bathroom in the gym, so everyone was cracking up as he was walking like a penguin back to class to use the crapper there. I think I heard a shart fart as he crossed the playground.
