EAT DIE!
A loud, funny insult that means you want someone to eat poop and then die. It's like the best way to make someone feel bad.
My mom said 'EAT DIE!' when I came home with a giant mess on my shirt.
My brother said 'EAT DIE!' when I took his favorite video game.
My friend said 'EAT DIE!' when I told his crush he had a belly button.
