School dances and bars all count.
As for me, never in school, I was the school nerd and avoided the parties like the plague. I didn't dance in public until my sister dragged my behind out onto the bar floor during her wedding after-party. Since then, I love it. (Always loved dancing, just was shy). I love to dance, but am afraid to without a partner for fear of looking straight out gay. (Wouldn't bother me in Europe, but out here I have to worry, especially since I'm trying to hook up with a girlfriend.)
