Sister Tom

The homosexual equivalent to an Uncle Tom. A homosexual who simply plays up to the stereotypes of how a homosexual is expected to act in order to gain approval.

After Robbie came out of the closet he keeps playing up how much he knows about fashion, but I really don't think he's even all that interested in fashion. He's such a Sister Tom.
