Brain Hack

To absolutely confuse or surprise someone, deliberately or otherwise, the the point of speechless amazement.
This happens often during such times as: Watching a far more skilled person than yourself perform an act, talking to a greatly profound, or possibly idiotic person, or most often, after a really, really good magic trick.

While watching that David Blaine special on TV, I got brain hacked, like, 20 times. How does he do that!?

brain slow

someone who cannot comprehend what is going on around them at that moment, but instead takes them a while to fully understand what actually happened.

Spencer Owens was a little brain slow when it came to everything in his life.
