eat my ass paper
You're telling the person to eat your poop paper like it's a birthday cake.
My sister said, 'Eat my ass paper, or I'll make you eat my ass paper every day.'
He texted me: 'Eat my ass paper, or I'll eat your ass paper in front of your class.'
My mom yelled, 'Eat my ass paper, or I'll make you eat my ass paper at the dinner table!'
