A man whose mannerisms make it obvious that he is homosexual--triggering most people's gay-dar--but lives a heterosexual, closeted lifestyle because of his LDS (Mormon) faith.
Lyle sure has an immaculate attention to detail, and ever since he saw the movie Juno he's always giggling about the term "pork sword." Even though he and his wife have sixkids, I think he's a total Mormosexual.
Someone who is both mormon and conservative, usually radically so, and therefore has no legitimate opinions in either religion or politics, regardless of level of education.
