It’s hard to underestimate you
This is very powerfull because it has no slurs, polite, does jot compare you to something like a 8 years old insult and makes you think about for a moment. When the meaning sinks in you realize its power and it hurts.
Insults that compare you to something aren’t that powerful.
Insults that describe you, like this one, have a great impact.
“Edomite!”
I was getting onto a bus, someone looked me over and spat out the word. It was clear from the tone that it was an insult, but it also sounded suspiciously bronze age, so I was very excited to find out what it meant.
Turns out it’s a biblical reference used by some black nationalist groups in the US to refer to white people as unclean or diseased. Edom was one of several late bronze age Canaanite kingdoms. At one point the torah describes them as slightly paler and dirty, hence the insult.
I stole it from Babylon 5, but “assassin of joy” is one I’ve used a few times
“Your opinion matters as much as anne franks drum set”
I told a cousin once I wasn’t going to be lectured on morality by a woman whose sole contribution to society was how much money she could spend at a liquor store. That whole post I wrote was honestly, according to my brother, some of the best criticism he’s read, quote, “You called her a lush without ever actually using the word, while also going up one side of her and down the other, saying everything the rest of us wanted to.” That cousin, to this day, will not interact with me at family gatherings.
I also once threw shitty advice I was given back into my boss’s face in my resignation text, to the point where he mentioned it felt “personal” when he called me to try to get me to stay. That was the resignation friends/family told me I should be a writer because, “You have a knack for telling people to go fuck themselves in a way where they thank you afterwards.”
My go to, though, when someone insults me is to usually respond, “I’ve been called worse by better.”
