Perpetual Dynamic Motion
Pertaining to or characterized by energy or generating an effective energetic action or process of being vigorously active or forcefully moving or being moved, continuing or continued without intermission or interruption; ceaseless in it's operation, driven by it's own force which gives it its own momentum regardless of any friction that is less than it's own force that is being applied. The basic rules for PDM (Perpetual Dynamic Motion) are 1. The design must use either gravity or magnetic fields, or use both gravity and magnetic fields. 2. The design must be symmetrical while exhibiting changing or moving parts to ensure the force of momentum is always greater than it's resistance. 3. The design must have a self contained push and pull or a self contained attraction and repulsion. 4. The design of the spinner must be lighter than the total weight or force that will be self contained to keep it moving. 5. The design will not be effected by any friction that is less than the total of its force, and even if stopped, it will self start on its own again and keep moving because it has it's own momentum.
The Urban Dictionary Tee

Not only was the product exactly what I expected, I was well informed on the shipping process in a seamless and timely manner!
The T-shirt was a birthday gift for my girlfriend and she absolutely loved it.

Happy that this tee is comfy and fits well. I wish the sentence was on the back too.
