Today's word is used mostly by the religious right for those who have 'left' their homosexual ways.

탈동성애자 (tal-dong-seong-ae-ja) 

So, what does 탈동성애자 mean? Understanding the word is quite easy. 동성애자 is a homosexual, and 탈 is the Chinese character 脫, which means take off or remove. The whole praying the gay away phenomenon. Yikes.

There is a website, KHTV, with youtube videos of 'ex-homosexuals' talking about finding god and throwing off their homosexual ways. Sigh.
