Brooklyn Boys (delirium tremens)

“Brooklyn boys” is 19th century slang for delirium tremens (DTs). The term has been cited in print since at least 1883 and the exact meaning is unknown, but it probably refers to Brooklyn’s many breweries. There is no evidence that the term comes from Gaelic.
 
New York City-born playwright Eugene O’Neill (1888-1953)  included “Brooklyn boys” in his plays The Iceman Cometh (1939), Hughie (1942) and A Moon for the Misbegotten (1947).
   
 
Wikipedia: Delirium tremens
Delirium tremens (DTs) is a rapid onset of confusion usually caused by withdrawal from alcohol. When it occurs, it is often three days into the withdrawal symptoms and lasts for two to three days. People may also see or hear things other people do not. Physical effects may include shaking, shivering, irregular heart rate, and sweating. Occasionally, a very high body temperature or seizures may result in death. Alcohol is one of the most dangerous drugs to withdraw from.

Not so with the man of brains,—a drunk of that duration paralyzes his system; he is unable to eat or sleep, his nerves are unstrung and soon the “Brooklyn boys” are chasing him, in imagination, from pillar to pillar.

Some call it an “hallucination,” but others less mincing in their language call it delirium tremens. No man will jump out of a two-story window—or attempt to do so—unless the “Brooklyn boys” are after hlm.
