We'll drink it out of the nipperkin, boys, Here's a health to the barley-mow!

A nipperkin is also one-eighth of a pint of beer or any other liquor.

The nipperkin and the jolly brown bowl, CHO.

Some versions replace these with "half barrel", and end with "nipperkin, and the brown bowl" or "round bowl" rather than "pipkin, and the drum bowl".

The nipperkin is a unit of measurement of volume, equal to one-half of a quarter-gill, one-eighth of a gill, or one thirty-second of an English pint.
