A nail through an olive is the only person who could make the moon cry. They’re the only one who got it down pat, and they do it with a little bit of arrogance and a lot of swearing.
My mom said, 'You’re like a nail through an olive. You got it down pat, and you swear like a sailor.'
In a text, someone wrote, 'You’re the nail through an olive. You got it down pat, and you’re full of yourself.'
At a fight, someone said, 'You’re a nail through an olive. You got it down pat and you’re full of yourself.'
