Self explanatory, a .GIF of a Jiggling Butt with "NN" one "N" written on each cheek. Or a Twerking Butt .GIF, same deal one "N" on each cheek.

Judges decision is final and no correspondence will be entered into, any one suspected of using a photo edit program shall be disqualified and reported to the authorities.
BONUS judging points awarded for a "Seamless Transition from finish to Start" as a .GIF is a continual ''loop'' without a start or finish.

Happy .GIFing
