Obsessive Compulsive Percussion Disorder

Also known as drummer's syndrome. Every drummer has it in some form or another. A person with OCPD cannot restrain themself from constantly tapping and drumming on any surface. Contrary to popular belief, it usually isnt controllable. If you ask someone with OCPD to stop tapping, they'll just do it quietly, and gradually increase the volume until someone yells at them so stop, and the pattern repeats.
You know that guy in your algebra/science/english class who NEVER stops tapping, ever? He can't control it, so leave him alone! And yes, i am a drummer with OCPD.
