The art of hiding an erection while sitting and leaning one's upper torso at a 45 degree angle betwixt one's chest and lap. The owner of said erection then proceeds to arch their back in such a way that makes them appear to be sitting upright. This causes said erection to recede into the body causing a "turtle shell" effect.

During sex, when a person is about finish first, their partner punches them in the face or back of the head, thus allowing the trailing person to finish first.

Usually will happen when it's cold out and your balls shrivel up nice and tight to get warm. (The wrinkles look like the pattern that a turtle shell could have)

Men who ride Harley's or other cruising type bikes, who wear turtle shell style helmets because they are not driving fast enough to need a full helmet usually. And they ride on a bike that has had custom steering handles installed. The handle bars are usually raised an additional 10 to 12 inches, making the rider appear to be hanging from a monkey bar.
"How bout that turtle shell on a monkey bar, his tiny helmet had huge skulls painted on it and he was barely able to hang onto his monkey bar because it was almost too high..."
