The paper explicitly states that they are calling ChatGPT "bullshit" in the Frankfurtian sense and they cite "On Bullshit" as the source for that definition. It's right there in the introduction.
You'd know this if you had read the paper or even checked whether your statement were true. So either you read it and then lied deliberately, or you didn't read the paper nor actually care about the truth value of your own statement, rendering your comment itself bullshit in the Frankfurtian sense.
