Not gay... It's a reference to an old sitcom involving two guys who dress up as women in order to live in a womens only building because they can't afford to live anywhere else. They're straight though. Basically all the hotels or motels in Ponyville could be full up except that mares only hotel and they could have only 1 room left. The show was called Bosom Buddies. It starred Tom Hanks and Peter Scolari. Hanks' character was in love with a girl played by Donna Dixon, who also lived in the building.
