What is "YGBT"?

I came cross the term in a Chinese forum. It seems that it has been used as a hate speech or self-label by both female transphobia and misogynist (very ironically) in Chinese Internet community, which refers to gbts who are against feminism. Some posts say it comes from English community, but I can find little English content about it, and most posts containing it are Chinese. So I wonder if you know the source of it? The post is about hate speech, but isn't aimed to spread hate speech so I think the post is okay.
