For Lesbians
Step1
Wear pink lipstick. No self-respecting lesbian wears pink lipstick, even if she sells Mary Kay in her spare time.
Step2
Carry an impractical purse with a chain handle, a snap catch and it's smaller than a sandwich. Even bull dykes know that zippers keep thieves out and checkbooks in, and that a chain handle will break at the first fumble for a pen. Plus, there must be room for tampons, credit cards and a cell phone.
Step3
Wear a cross. While lesbians come in every denomination (Christian, Jew, Muslim), your average straight person will assume a cross-carrying Christian can’t be gay.
Step4
Mention a boyfriend, husband or fiancé. Heterosexual assumption dictates that every woman wants one, why would you be any different unless you say so?
Step5
Skip sensible shoes. Remember Robin Williams in “Good Morning, Vietnam”? Everyone knows that lesbians wear sensible footwear, so tripping along in kitten heels should fool the world.
For Gay Men
Step1
Get dirty. Gay men are clean and tidy, according to conventional wisdom, so skipping a shower every other day and smudging your glasses should mark you as straight.
Step2
Mention a girlfriend, wife or fiancée frequently, but do so in an off-hand, taking-her-for-granted way. Most straight men talk about their wives less ardently than most gay men talk about their female friends.
Step3
Wear your team affiliation on your chest. While a gay man may love baseball, football, soccer or basketball as much as a straight man, he seldom feels he has to dress like a groupie to say, “Go team!” Wearing sweatshirts, baseball caps or torn t-shirts sporting a team insignia will effectively mask homosexuality among strangers.
Step4
Hide your light under a bushel. Shuffle, slouch, avoid eye contact, rhythmic movement or breaking out in song. Straight men tend to be less expressive than gay men, with the exception of theater majors, who are all assumed gay anyway, no matter what their girlfriends say.
Step5
Mess up your home. If you have to pass as a straight guy on your home turf, make sure it is unkempt, untidy and smells of testosterone. Invite over a handful of your heterosexual male friends beforehand to stink up the place if you're too fastidious to add odor on your own.
