macaroni - A threat you throw at someone when you have no idea what you

A threat you throw at someone when you have no idea what you’re doing. It’s like you’re trying to scare them but you’re just making it up.

I said, 'I’m gonna macaroni you,' and I had no idea what that meant.

He threatened me with macaroni and then ran away.

I told my mom I’d macaroni her, and she just laughed.
