A meal composed entirely of meat and food rich in protein. Created to give pirates their energy during their plundering. It was usually packed for portable consumption, hence the Lunchbox part. Is now used to refer to a lunchbox for kids that don't like vegetables.
Mom: Billy, I've packed you celery sticks and peanut butter for lunch.
Billy: Aww, I wanted a Pirate's Lunchbox.
