a modest proposal
A Modest Proposal is when something sounds cool but is actually gross. It’s from a book where someone said we should eat babies. It’s like saying, 'This is a great idea!' while eating a baby.
My teacher said, 'A Modest Proposal! Let’s eat the class!'
My brother said, 'I’d eat your sister for lunch!'
My mom said, 'If you don’t clean your room, I’ll eat you!'
