EAT DIE!
When you're so angry at someone you want them to eat poop and then die. It's like the end of the world for that person.
My brother said 'EAT DIE!' when I took his favorite video game.
My friend screamed 'EAT DIE!' when I told his crush he had a belly button.
My mom said 'EAT DIE!' when I left my room in a total mess.
