Lol. I had to look it up on Wikipedia. I had NO idea! I do like the term though, but unfortunately I fear it will never penetrate the wider community that thinks the best way to describe gender is through one-dimensional lenses of “straight/gay acting” and “ladylike/butch”.
The first time I mentioned it to a guy who called himself “straight acting” he threw the biggest tantrum at me (gurl!) because he thought I had just called him a “sissy”!
