eat their shit
When you eat your food and your poop at the same time, usually while sitting on the toilet. It’s like you’re having a party in your pants.
I ate my sandwich while I was going to the bathroom. I was having a full meal and a full poop at the same time.
My friend eats his food and his poop at the same time. He looks like he’s having a party in his pants.
I had a big meal and then I had a big poop. I was eating my own shit like it was a snack.
