Eat it like a horsey
When someone gives you a little bit of food, but you have to eat it off their hand like you're a hungry raccoon who just got kicked out of the trash can and now wants revenge.
He gave me a slice of pizza and said, 'Eat it like a horsey or I'll throw you in the pool.'
She made me eat a crumb off her hand like I was a baby who just got fed by a monster.
I had to eat a piece of candy off his hand like I was a dog who just got hit with a broom.
