Eat my shit!
A short and dirty way to tell someone off when they're annoying you. Just say it and walk away like you're the king of the world.
My friend said, 'Eat my shit!' when I laughed at his bad joke.
My neighbor yelled, 'Eat my shit!' after I threw a rock at his cat.
My crush whispered, 'Eat my shit!' when I said I didn't like him.
