I'm not gay
a comment used by insecure males to lead others in to believe that they are straight when they are actually bisexual, thereby making the comment true: a person who says "I'm not gay" is neither straight nor gay, but bisexual
Jimmy: "That guy just came up to me and said, 'I'm not gay, man'. I wonder why he would do that." Maura: "He was letting you know he was bisexual, dear. You should go back up to him and ask him if he would like to see a movie with you tonight."

Kurt: "Ram, I was wondering. Uh..."
Ram: "KURT, I'M NOT GAY!"
Kurt: "Sweet! What time?"
Ram: "Maybe like six or something. I'll pick you up!"
