Saint Knickers 

A term for the special undergarments Mormons wear under their regular clothes after their first temple endowment session. They are expected to wear them at all times except for certain circumstances.

Fred: Mormons are the ones who wear the funny underwear, right?

Shaggy: Yeah, I call their underwear Saint Knickers.
