gaggle of nuns
Nuns who have left the church to do something weird, like hang out with kids or eat ice cream in the middle of the day.
A gaggle of nuns was found in a park eating ice cream and laughing like they were teenagers again.
They were seen at the movies whispering prayers during the previews.
A group of nuns was caught eating pizza in the back of a gas station like they were on a road trip.
