To hide any object, or drop from conversation, anything that the Pope might find offensive if he hypothetically was to come over for dinner. Often invoked for visits from parents, co-workers, parent evaluators, or anyone else, where significant ramifications could occur from your friends outing your drug, sex, and alcohol lifestyle.
My parents are arriving in town tomorrow and want to see our place. Hide the bong, we need to switch to pope mode!
