In my humble experience, bullshitters are the easiest people to take advantage of, because they believe they have to be open to your bullshit for you to be receptive to theirs. Skillfully used, this can be utilized into taking points of their bullshit to strengthen the stench of yours.

What's really impressive is when you watch two seasoned bullshitters go toe to toe. Their smiles get bigger and bigger as things get more intense (threat display behavior), and the volume increases while the tone deepens as both try to appear to be "serious guys". Eventually there's a backslapping of the loser and a crushing handshake, along with plans to meet that will never be followed through on.

It's very similar to how internet troll minds work. They're literally the easiest people in the world to reverse troll, as they're so desperate for attention that they'll jump on any opportunity to gain yours.

EDIT: Aww - that's cute, one of my trolls showed up to downvote me and prove my point. What's wrong @some_guy, feeling lonely today snookums?
