A form of ritualized drinking. When you have a cup, can, or bottle of the beverage of your choice, the pack will sing a song with the words ``drink" or ``down" in it. At that point, you should start drinking. You will continue drinking until one of two things happen:
- you finish the beverage, and you turn the cup over on top of your head to show that it's empty, or
- you don't finish the beverage, and you pour the rest over your head to show that it's empty.
