Fill The Bag Edit Meaning

1.

Trucks driven by many long-haul professional drivers don't typically have a restroom, and it's also often not convenient to find a rest stop, etc, when nature calls. What to do? A good buddy of mine merely stops beside the road, gets out his super-strong scented plastic garbage bag, gets into an appropriate squatting position, and lets go.

Time to stop and fill the bag.
