Coming Straight Story

"Norm: "I can't go on with this any longer. I wanted to be your decorator, so I pretended to be who I thought you wanted me to be. but it's time I came out of the closet. I'm straight."

Robert: "Impossible."

Norm: "Ever since I was a little boy I've known that I prefer girls. But the point is I think you should judge people for what they do, not for who they do.""

- Cheers, "Norm, Is That You?"

A straight character is believed by everyone within a group to be gay. Eventually, that straight character "comes out", and admits to the group that they are, in fact, straight. Nearly always Played for Laughs, this is a very common inversion of the typical Coming Out Story, where a closeted gay man or lesbian finally admits to their heterosexual friends and family that they are homosexual.

Where a Coming Out Story is frequently a serious event within a character's life, with friends and family sometimes being initially unaccepting of the revelation, a Coming Straight Story almost always involves the gay friends rapidly coming to accept the fact that their friend is straight. Typically involves a straight male character in a profession in which homosexuality is the stereotypical expectation.

Often also serves the purpose of a Gay Aesop about being open-minded and accepting of those with a different sexual orientation, although this may be undermined by the trope being Played for Laughs. Also serves as an Aesop that Honesty Is the Best Policy.

Often a result of Mistaken for Gay remaining uncorrected, or due to a character intentionally being Camp Straight. Occasionally applied directly upon the character being Mistaken for Gay, although this is usually less effective. Can only arise in the absence of a character with Gaydar. Sometimes Invoked by a character in order to get a laugh from other characters. Contrast with a successful case of Cure Your Gays, where a character that was gay is turned straight and thus "comes straight" in a different sense.
