Unload Some Groceries
To take the nastiest, filthiest, wettest dump in a paper bag and then slap someone in the face with said bag. Works best when bag has had time to soak and get soft and soggy.
Wes tried to unload some groceries on that dude, but the bag ripped mid-swing and spattered feces all over the bystanders and they started gagging and wretching, followed quickly by vomiting on each other en masse. What a night.
