galloping piles
Grade 4 piles are like your butt is on strike, and you have to run like a madman to the nearest cream to bribe it back inside
My piles went on strike during lunch, so I had to run to the store like I was being chased by a feral raccoon.
My piles are so out that I had to sprint across the parking lot like I was in a race against a giant, smelly donut.
At the grocery store, my piles came out like they were on a mission, and I had to run like a maniac to find the nearest cream.
