Eating liver
You're so hungry and sick of everything you’ve ever eaten that you're ready to chomp on someone's liver like it’s your last meal.
I'm that hungry I'd eat my teacher's liver if she didn't give me detention first.
I'm that fed up I'd eat my best friend's liver if he didn’t make me wait for it.
I'm that desperate I'd eat my pet's liver if it didn’t look at me like I was a monster.
