Does wearing a pinkie ring on the left hand mean your a lesbian?

No.

The only jewelry that means you are a lesbian is if you have a necklace pendant with the letters "I am a lesbian" on it.

There is a never-ending list of supposed cues. In the mid 1980s, wearing green on Thursdays was one. These are apocryphal, and do not actually mean anything.

Ironically enough, you might now hear a young mother worrying about which ear gets an earring on her young son and deciding that TWO earrings will avoid the issue safely.
