Eat Your Hat
You yell this when you're so angry you could spit nails. It's like telling someone to choke on a flaming burrito and then you laugh in their face.
"Eat your hat, you worthless piece of garbage!", after your cousin stole your last pizza slice.
"Eat your hat, you failure!", when your friend beat you in a video game.
"Eat your hat, you loser!", when your dog ate your homework.
