Probably not. But if you have children or grandchildren, or your church calling involves working with kids, you can likely guess how such terms originated.
As children grow up in The Church of Jesus Christ of Latter-day Saints, gospel-related words don't always register accurately, and what translates to those little ears can make for heartfelt humor and lasting memories. Whether the result of a misheard hymn, where parents are "kind of weird," or an innocent interpretation of a gospel concept, like "slow Sunday," stories about children in the church tend to endure.
