A man who is clearly gay but chooses to the live a lie and pretend he is straight by marrying a female who is clearly lacking in common sense and social intelligence. She will never admit to her dissatisfaction with their virtually non-existent sex life and continuously praise his fantastic interior decorating capability and revel in his commensurate passion for musicals.
You know this guy...we all know this guy, or at least his wife and we just aren't telling her dumb ass. "Oh that's her husband?! I thought for sure he was gay. What a gary!"
