Bullshitting is manipulative storytelling. Some of what a bullshitter says is true. Some of it they even believe is true. Some of it they desperately want to be true. What's outright false they would say is unimportant and deflect rather than argue about. But they're saying it to get something they want or avoid something they don't want, and they'll tell any remotely plausible story to make that happen. Bullshitters change the story to fit the situation, often in real time as it develops. Lying is more straightforward in that the liar is saying something they specifically know is not true to deceive the listener.
