I look like a butter - To look like a butter is when you're so clean you could mop

To look like a butter is when you're so clean you could mop the floor with your face.

I washed my face so much I looked like a butter and could mop the floor.

My sister said I looked like a butter, but I know she was just being mean.

I came home from the beach and my dog said, 'You look like a butter, I want to mop the floor with you.'
