The extremely close relationship between a homosexual and a heterosexual of opposite sexes. Either a homosexual male and a straight female, or a Lesbian and a straight male.
Jim was dating around in the gay community, and Amy was on and off dating a gentleman, yet Amy and Jim hung out almost constantly. They shared very similar views and outlooks, and had a very very strong friendship. Thier Mo-mance was something that not many people understood.
