nah, I'm not going to let that confuse me because it took me years to make some sort of association in my mind to remember which symbol meant what. All I remember is that since I'm a woman and I'm attracted to men, I point to men, therefore the arrow means men. I can't remember anything else beyond that. other than using the process of elimination to figure out the other ones.
It comes from Roman mythology, it was a symbol of Mars and is supposed to represent a spear and shield. I had to look up what the female symbol represents, allegedly it’s the hand mirror of Venus. I would bet it’s not a coincidence that they can be viewed as abstract genitals, though.
When I was growing up I never understood nor was I ever told what those symbols met, the first time I saw them was in fireboy and watergirl and my first thought when seeing them was exactly as described in the meme, which confused me because both fireboy and watergirl have bodies and neither of them have horns.
Well it was meant to be the symbol for mars so not far off. I don't get the female one though, no matter how long I look at it it just looks like a legless stick figure.
I got no sources to back it up but I've taken that as a fact for very long time: the symbol for Mars (male/masculine) is a shield and a spear. The symbol for Venus (female/feminine) is a handheld mirror, that cross under the circle is the handle.
