This hardcore sex move occurs only during sunrise anal intercourse. The man plows the girls ass so hard that she pinksocks to the point that it casts a shadow across her asscheek.
This is best celebrated during Groundhog Day every Feb 2nd.
Damn, I gave my girl such a big Punxsutawney Pinksock that it saw its own shadow. Now I won't get laid for six weeks.
