With no malicious intent (which can always be construed whether I say this or not), I call any two guys or gals, who seem to be always together at events or whatever, when I refer to his or her other half, asking about the other person, I will always say "Hey man! Where is that gay partner of yours?".
Some will play ball and answer it good naturedly but some do take offense of this and protest vehemently that they are not gay and they are not a partner. I usually just smile back and ask back, "If you are not gay, and is comfortable with your sexuality, what is the problem? Will girls suddenly wouldn't like you when they heard me saying you have a gay partner.
As this is Malaysia and last I heard, there are still more heterosexual than homosexual (if what I know is correct) and I bet all women love to 'turn' any one of those handsome homosexual into a red blood heterosexual male. Especially in view of most men being too crude for their taste.
Hey, even I have a few 'gay partner' that my wife even mentioned that I always drive by a house of one of this guy I always hangs out with so that I might into him, just like a lover driving past his or her lover's house.
This note is more biased towards gay as in between men and men as women are more intimate with each other even with their best friend in contrast with men.
