John Logic™ refers to someone who thinks they are extremely educated and above all else smarter than their peers. They believe this because they will talk circles around their opponents in any debate they are having to the point of exhausting them into giving up. They can always defend their actions by using this strategy.
It's not even worth telling him how bad that trade was, he uses John Logic™.
