When lacking in a gay friend; the chosen selected male to fill this void in a group of females. This male will rarely accept his role as the gay friend whose responsibilities include fashion consult and drama queen, so it is necessary to keep their designation as a personal joke for as long as possible. Once the cat is out of the bag, tell them they are allowed in dressing rooms, cause, well, they're gay! *wink*
