Bagjuice is a softdrink (non-alcoholic) in a plastic bag. The liquid is usually homemade from natural fruitjuices put on ice cubes in the small plastic bags and carried on expedition/boat/beach trips. To drink the bagjuice it is pierced by the straw you drink with.
Instead of carrying heavy softdrink bottles on trips an ice container filled with bagjuices is more practical, it takes up less space and is environment friendly.

The indeterminate liquid, whether from drinks discarded in the the trash or from decomposition of other materials, found in the bottom of a trash bag, esp. one located in a public place.
Joachim carefully lifted the trash bag out of the garbage can, but there was a hole in the bottom of the bag and some bag juice leaked out on the floor.
