The words were but out of his mouth when John Harmon lifted his finger, and Sloppy, who was now close to Wegg, backed to Wegg’s back, stooped, grasped his coat collar behind with both hands, and deftly swung him up like the sack of flour or coals before mentioned.
After the commotion and the heated debate, Sloppy grabs Wegg by the collar and literally throws him out of the house. Weggs' body lands right into some sort of trash cart that's out in the street. Charles Dickens brilliance for metaphors is hilarious and yet accurate to the story and the situation yet again, basically this moment basically illustrates a good bye or at least a aggressive see you later to Mr. Wegg.
