Eat my shit!
A super rude way of telling someone to kiss your butt, but even worse. You shout it when you're furious and you want to make that person feel like the biggest loser ever.
My mom said, 'Eat my shit!' after I spilled my cereal on the floor and ate it anyway.
My brother yelled, 'Eat my shit!' when I took his last cookie without asking.
My teacher screamed, 'Eat my shit!' when I drew a mustache on her face.
