Turtle-Move 

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"

Turtle Knock 

When two penis heads touch together.

This most commonly happens during a threesome via an act called "double penetration" when two males accidentally pull out at the same time and knock the tips of their penises together. "Hey bro, I didn't mean to turtle knock you last night, It was a total accident."
