eat my ass paper
You’re giving the person a paper full of poop and telling them to eat it like it’s a snack.
At the bus stop, my cousin said, 'Eat my ass paper, you loser!'
My brother left a note on my pillow: 'Eat my ass paper, or I’ll eat your ass paper.'
My teacher wrote on my test: 'Eat my ass paper, or you’ll fail.'
