I think they actually call it “sucking a limp dick”. Really, they want it to be different than sending a tweet or sending an insta, so they say, “hey my bros, I was just logging into truth social and I had so many uneducated things to say, yeah, I sucked so many limp dicks on Truth social, it’s insane my bros!” or “hey that child getting vaccinated really makes me angry, I’m going to suck a limp dick about this so friggin much on Truth social!”
