Used to confuse someone in the process of making a counter-clockwise maneuver, causing them to reverse direction against all logic and reasoning. The grinding of mental gears ensues as the individual instinctively reverses direction, thus moving clockwise, even though the suggested "correction" indicated a change to counter-clockwise. Tons of fun at parties.
*someone passes the joint counter-clockwise, away from you*
"No dude, COUNTER-clockwise!"
*the individual reverses direction and passes you the joint*
