nouveau gay
Describes the behavior and state of mind of a person that's newly "out" as a homosexual or bisexual, in particular the tendency to delve into all things gay or alternative as a result of his or her newfound self-confidence.
"You wouldn't believe Mike these days. He's so nouveau gay that all he talks about is gay performers, gay films, and attending the gay pride parade. You'd think he had no life outside of his sexual orientation."
