"inept person; old man," especially "bad golfer," 1842, perhaps from Scottish duffar "dull or stupid person," from dowf "stupid," literally "deaf," from Old Norse daufr, with pejorative suffix -art. Or perhaps from 18c. thieves' slang duff (v.) "to dress or manipulate an old thing and make it look new."
