7.
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?
