>>4014968OK, I was able to dig a little deeper. The term cute aggression didn't exist anywhere before January 2013. And when it did appear, it was already being used to refer to the normal urge to harmlessly squeeze and pinch cute things. It appears to have been coined by two Yale grad students translating a Tagalog word, gigil, into English.
The understanding of it as a negative, actually violent thing seems to be limited to 4chan. The main catalyst was a thread on an altchan from 12/31/2018 that was reposted on /pol/ a few days later. I also misremembered. The OP of that thread posted a link to the 2015 study on "dimorphous expressions". But he apparently didn't read it because pretty much the entire post was misunderstanding what it was about. This is when it was reframed as a hatred of cuteness/beauty and associated with low IQ.
There were posts before this using cute aggression to refer to more violent desires. But these retained its original meaning tied to an overwhelming cuteness and were typically used by anons to refer to themselves with no stated hatred of the cute character and no association with IQ. They mostly seem like people being edgy/extreme, as is often the case here, with it occasionally being misattributed to actual sociopaths. It was likely these latter mistaken uses that led to the creation of the /pol/ thread.
