abstract:"Seeing pink elephants" is a euphemism for drunken hallucination, caused by alcoholic hallucinosis or delirium tremens. The first recorded use of the term is by Jack London in 1913, who describes one kind of alcoholic, in the autobiographical John Barleycorn, as "the man whom we all know, stupid, unimaginative, whose brain is bitten numbly by numb maggots; who walks generously with wide-spread, tentative legs, falls frequently in the gutter, and who sees, in the extremity of his ecstasy, blue mice and pink elephants.
