look up any word, like cleveland steamer:
 
1.
A gutsy attempt at completing some ill-advised feat of physical dexterity. While the attempt will most likely ultimately end in complete and utter failure (with the participant on his/her back, feet and arms in the air, like a TURTLE turned upside down), the fact that the feat was attempted in the first place will be celebrated.

What makes it a TURTLE-MOVE is an extremely low chance of success and an almost assuredly high rate of personal injury.
"Man.... that attempted 180 on the tightrope was a real TURTLE-MOVE!"

Can also be used as a warning to others - "Be careful out there.... no TURTLE-MOVES"
