turtledick 

When in a state of anxiety or after having been struck in the genitals, the penis tends to retract into the body. The name is derived from the turtle's defense mechanism.

Also applies to the bodily response after having gone swimming

I just went for a swim, and I got a mean case of turtledick (or turtlecock, tortoise-shlong)

TurtleDick 

The inverted crawl of the male genitalia much like when a Turtle hides his head in his shell. This happens when you spot a woman that once was hot enough that you would have had sexual relations. Now she is such a fright with an additional 40lbs and an extra set of breasts on her back. Just the thought of her makes your penis crawl back into your groin.

Oh my God did you see her? She is such a mess, Just thinking about her gives me TurtleDick. What Happened to her?

Zurtledurk 

are evil horrid monsters, live in the mud, fly at night, eat the worms, make a terrible noise. They are the evil characters in a fairy story.

“The Zurtledurk is such a terrible sight”
Said the Tumshee, her little face pale.
“It lives in the mud and it flies in the night
And eats Tumsheeworms, head, feet and tail!
