A process where gays publicly expose gays who aren’t out of the closet. Sometimes done in a petty and nasty way to slap down a gay person who remains in the closet, sometimes done to show the straight world that some of its biggest stars are really gay, and sometimes done to expose anti-gay public figures who are gay. Used in a positive way when referring to your own person, as in “I outed myself to my family and friends, and I couldn’t believe they weren’t surprised.”
