look up any word, like fellated:
 
1.
The built-in biomechanical mechanism in which Mormons can automatically sense other Mormons in the immediate vicinity. Similar to GAY-DAR, but this is of a more divine inspiration. IF you hang around Mormons long enough it can morph over to you, through the process of osmosis.
1.) Tyliqua's Mor-Dar was in full effect today.... He told me there were Mormons at the door before I even opened it.

2.) Q: Shauna can seem to spot Mormons a mile away. I wonder Why?
A: She has Mor-Dar. But since she no longer in the church, it has been converted to Jack-Mor-Dar.
