It is a made up "fact" by someone on twitter: that JD Vance wrote about fucking a couch in his book, Hillbilly Elegy. Some people retweeted it without checking the sources, and it just continued on from there.
Source is knowyourmeme lol: https://knowyourmeme.com/memes/jd-vance-couch-cushion-story-hoax
So like just like academic scholars?
