When you gotta shit real bad, and the terd comes part way out, see's his shadow, and goes back in the hole.

During sexual intercourse, you witness something so incredibly disgusting that you lose your erection and your penis recedes in towards your body. (Much like how when a groundhog notices his shadow and runs back into his hole.
I was about to start fucking this girl I met at a bar, when I pulled down her pants and noticed she had open sores covering her pussy. It was so disgusting my penis went groundhogging.

Similar to "prairiedogging", this is when your poop is so large that it comes out, sees its own shadow and goes back into hiding until you can find satisfactory facilities.

Like in the movie Groundhog Day where you keep reliving the same day over and over except there isn't anything good about it and there is nothing but dismay.
