rainbow catcher 

A person who has an abundance of homosexual friends. A rainbow catcher may be confused with a fag hag, but the rainbow catcher accepts and understands that their gay friends will not convert to the heterosexual side. Also, this term is not derogatory.

I really dislike the term "fag hag", yes I have many gay friends, but I am a rainbow catcher.
