Circean poison

noun

A draught of any kind that is magically and fatally infatuating, such as applause. The expression is named after Circe, from Greek mythology and particularly from her actions in the The Odyssey, when she tempted men to excess before turning them into pigs.

O foulest Circean draught, thou poison of Popular Applause! madness is in thee, and death; thy end is Bedlam and the Grave.
