The "Question Hour" is a state of utter pandemonium that leads to the abandonment of a planned activity.
Taken literally, it refers to a time designated in Parliament for the asking and answering of questions. However, it often becomes an occasion for angry lawmakers to vent other grievances while the beatifically-smiling Speaker murmurs, “Take your seat please; please, take your seat,” and invariably leads to a rapid adjournment of the session in question.
Person B: I tried to go in the evening but it was total question hour.
