- noun prison. This term from the beginning of the 19th century is usually part of the phrases ‘in jug’ or ‘in the jug’. It probably derives from 18th-century dialect jougs, meaning stocks or pillory (from the french joug, meaning yoke), rather than from jug as a container of liquid. In modern usage the term is jocular.
- verb to imprison. From the noun jug.
- verb to drink, usually to excess. The phrases are probably influenced by the categorisation ‘jug wine’, denoting cheap wine bought in large containers, e.g. by students and other drinkers of modest means.
