Turtle Shelling

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.

"Dude, my Spanish teacher is so hot...she had me turtle shelling all class."

Clam Shelling

A medical procedure during which you put on a 15 lb lead cannonball shape module around your testicles to protect them from irradiation. While the procedure is quite cold and difficult to not pinch yourself, it is not that hard as long as you are not attempting to put your penis inside the module.

Patient: "Gahhhhhhhhhh. Phew, Nurse I swear to god this is so difficult, but I have finally completed the Clam Shelling!"

Nurse: “You...uh - you don’t …. uh … You don’t actually have to put your penis in it?”
