Usage notes[edit]

The phrase implies that the quality of work done or goods sold is shoddy enough that the person responsible must leave town under cover of darkness to evade angry customers, or sometimes legal authorities. The earliest use of the phrase is said to have been a reproach for women, signifying that she was a witch.[1] The modern usage first appeared in 1823.[1]
