Some singer called Charli released an album called Brat. And some fans decided it was "Brat girl summer". Charli subsequently tweeted that Kamala is brat after her candidacy was announced and doing well. Harris' campaign team changed her banner on Twitter/fb to the same green color as the album for a time after the tweet. Fuck if I know why anyone cared about this.
Someone faked an excerpt from JD Vances memoir "hillbilly elegy" stating that Vance had admitted to fucking a kleenex box between some couch cushions. For obvious reasons the internet decided that this was very memeable and ran with it.
The couch fucking really exploded when the AP put out a fact check saying he "didn't have sex with a couch", but then retracted it because they can't definitively say that he has never, in private, had sex with a couch
