A non-practitioner of the Mormon faith, aka LDS. One who was “born” into the Mormon faith, but persists with their “sinful” habits and addictions (such as Jack Daniels liquor). Popular in the Southwestern U.S.
Don’t let Keith fool you. His whole family are all “Jack Mormons.” They are at the casino drinking every weekend.

Any class of hypocritical, self-righteous bastards that are members of the Church of Jesus Christ of Latter Day Saints and are prim and proper on Sunday morning and in front of other Mormons, but swear like sailors at work, secretly drink like a fish, cruise the net for kiddie porn on their work computers and are man-whores all over town.
"Always take at least two Mormons fishing with you or the damned Jack Mormon will drink all your beer"
