A condition where an individual isn't a
mormon, but acts like he/she is by not doing drugs, alcohol, or before-
marriage sex. See Also Strait Edge.
A condition where an individual isn't a
mormon, but dresses and often looks like one.
Dave seems like he doesn't do drugs, drink, and is a virgin. Is he a
mormon? No, my friend told me he's not, and that he's got mormonitis.
Then I saw Dave ride his
bike on the side of the road. I thought he was one of those mormons who ride their bikes while dressed nicely, and wearing backpacks and nametags. But since Dave isn't a
mormon (he wasn't wearing a nametag), then it became obvious that he had mormonitis.
