Get one's hump up is an old-fashioned slang phrase meaning to become irritated, angry, or sullen — to get your back up, as a cat does when annoyed. The hump here evokes the raised spine of a bristling animal or the hunched posture of someone in a bad mood. Though archaic in most modern usage, the phrase still turns up in period fiction and occasionally in regional speech where older idioms survive longer than average.
