"despite what you may have heard, pusillanimous does not serve as the basis for pussyfoot, pussycat, or a certain related vulgarism." - Merriam-Webster Dictionary
Social media yes absolutely is, but so is the Internet in general. There's always been conspiracy and other whacko websites. Social media just brings the misinformation to you, instead of previously, you had to seek out that kind of content.
Also, ask a random selection of people who call other pussies what they mean by it. I can guarantee you that the mayority is referring to the body part. Which makes this stupid.
I was always thought about it was cats because they're scared and shit.
But holy fuck, never fuck with a cat that hates your guts and wants nothing to do with you.
Hmh. I have never called someone a pussy, but when people do, I ususually do think of the body part. Based on this, I postulate that we are polar opposites.
I'm not an ethymologist, but I remember looking around when this last came up, and while there weren't really any fully authoritative sources, the consensus seemed to be that the insult referred to the body part, and the existence of an old-timey word that sounded similar was a fun coincidence.
"pussy" as in coward and "pussy" as in vagina are both references to cats. pussycats.
we call cowards pussies because cats scare easily.
we call vaginas pussies because they are soft and delicate (not actually, but that's how we want to treat them)
this doesn't have to be a misogyny thing, and anti-misogyny thing, or an anti-anti-misogyny thing. everyone just fucking chill out about this word, ffs
