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?”
