Carouse the hunter's hoop.
Drinking cups were anciently marked with hoops, by which every drinker knew his stint. Shakespeare makes Jack Cade promise his friends that “seven halfpenny loaves shall be sold for a penny; and the three-hooped pot have ten hoops.” Pegs or pins (q.v.) are other means of limiting the draught of individuals who drank out of the same tankard.
