Turtle Shell

When your balls shrivel up into your abdomen, leaving the scrotum looking like a ridge-textured turtle shell. This is commonly caused by either exposure to cold or in those situations that give you the willies, much like goosebumps.

I stepped into the pool, as soon as my balls touched the water, immediate turtle shell.
