A dump resembling when a grocery bag is overfilled and the bag rips, immediately dumping all of its contents at once. Grocery bag dumps usually occur after large meals and waiting until the last minute to defecate.
I'm glad I made it to the bathroom in time. I had to take a massive grocery bag dump. I feel much better now.
