Sense 2
a "modest quencher," taken the morning following a debauch. Originally a "HAIR OF THE DOG that bit you." This is very old, and seems to show that homœopathy is by no means new, so far as topers, at all events, are concerned.
Một loại rượu uống vào buổi sáng sau một đêm say
Machine-translated — suggest a fix
