The word scabrous can describe anything that's bumpy and coarse, like your pet iguana or the rough stucco walls in your parents' house.

The adjective scabrous is also used to describe things that are considered lewd or obscene, like a scabrous newspaper cartoon that manages to offend everyone who sees it. The Latin root, scaber, means "rough and scaly," and is closely related to scabere, "to scrape."
