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 just about to bang this hot chick last night when she farted. It was so gross, i lost my erection and my dick went groundhogging.
