The series revolves around a low-class worker turned into drugdealer and a noble-blood woman turned into a police captain, who seeks for justice and revenge of her father's death.
The phrase developed among low-class shopkeepers and can be used today to greet a business proprietor in a friendly and familiar way but is not a universal greeting.
It enjoyed a considerable vogue for several centuries, being associated with low-class entertainment, especially of a salacious sort, though also used for moralizing and other serious verse.
