Full habit

This can be interpreted as gross men of vulgar tastes: boors, oafs, and lumpkins. Hyder (161) says that "of full habit" is an old expression meaning fat. This is borne out in Captain Marryat's novel Peter Simple (200) in which a 250-pound man is described as having a "full habit of body."
