I heard them use jokes I’ve only heard on Hexbear, but I kept chalking that up to “maybe this is just leftist twitter humor”. Now, I’m casually listening to the latest episodes and one of the hosts made a throwaway line about lathing something into existence. There is no way that bit is used anywhere other than Hexbear.
The joke about lathing things into existence originally came from an old episode of Chapo I think, and the subreddit turned it into a thing.
