Back before dating apps like grindr, guys met by hanging out in internet chatrooms. And before internet chatrooms, they met by posting or answering personal ads in gay magazines.
Every gay magazine had a "personal ad" section. The Montrose Voice in Texas, Frontiers in West Hollywood, The Edge in New York, even The Advocate.
My friends and I had lots of fun reading and discussing the new ads every week. We didn't respond often -- who needed to respond to a personal ad when you lived in a gay neighborhood?-- but occasionally one stood out as particularly promising, and we made the call.
We quickly learned to decipher what the code words really meant.
Many of the code words are still used today, in profiles on gay dating sites and the personal ads on Craigslist.
