lunacy
Utter senseless behavior
Lunacy is extreme foolishness or reckless disregard for consequences: It would be sheer lunacy to attempt the climb in this weather.
The word originally referred to intermittent insanity supposedly caused by phases of the moon—hence the connection to lunar.
The older psychiatric sense has faded; what remains is emphatic condemnation of foolish behavior.
