    What bullshit essentially misrepresents is neither the state of affairs to which it refers nor the beliefs of the speaker concerning that state of affairs. Those are what lies misrepresent, by virtue of being false. Since bullshit need not be false, it differs from lies in its misrepresentational intent. The bullshitter may not deceive us, or even intend to do so, either about the facts or about what he takes the facts to be. What he does necessarily attempt to deceive us about is his enterprise. His only indispensably distinctive characteristic is that in a certain way he misrepresents what he is up to.

    During a typical Gish gallop, the galloper confronts an opponent with a rapid series of specious arguments, half-truths, misrepresentations, and outright lies, making it impossible for the opponent to refute all of them within the format of the debate.[2] Each point raised by the Gish galloper takes considerably longer to refute than to assert. The technique wastes an opponent's time and may cast doubt on the opponent's debating ability for an audience unfamiliar with the technique, especially if no independent fact-checking is involved, or if the audience has limited knowledge of the topics.[3]
