eat their shit
When your friend or someone you’re watching decides to eat something so gross it looks like poop. You’re just happy they’re eating it and not you.
My friend tried that spicy ramen. He looked like he was eating his own poop and loved it.
My sister took one bite of that lasagna and said it tasted like her dog’s business.
My brother ate that taco and said it was the worst thing he’d ever eaten. I laughed and said, ‘you’re eating your own shit.’
