I'm gay, and a friend and former colleague went through a period of regularly endorsing me with anything that sounded at all that could sound either camp or gay. I can't seem to figure out how to find them now, and off the top of my head the only one I can think of is Pearl (I'm not a programmer, and I doubt he even knows Pearl is there as a programming language). Meanwhile I'd return the favour with anything that hinted towards the fact that he's a massive pervert.
Was great fun for a while, and the only use I've ever had from endorsements, which I've now completely disabled.
