I thought it just ended up sounding gay. But no, it’s gay. [The bit about coming out of the closet should have tipped me off. :p] It’s from the La Cage aux Folles musical, which is about gay dudes, and it happens to have been written by a gay dude. It turned even gayer when Gloria Gaynor did a single of it.
P.S. How awesome [+ hot] is Gloria Gaynor?!
