A description of the spin direction of a flying disc. Short for clockwise. When describing spin direction, it is customary to use a top down perspective of the disc. A disc that appears to be spinning clock from the top will appear to be spinning counter from the bottom, hence the top down perspective is used no matter the vantage point. When a disc is upside down, the top down perspective is still used. Thus when a disc is turned over, its spin direction reverses. For a disc that is tilted, use the side that is the most upward. For a disc that is perfectly perpendicular to the ground, use the top side of the disc.
Example: Throw me some clock.
