An earthquake that occurs on Valentines Day due to many people having sex at one time. The earth's rotation is initially affected, then the earth's tectonic plates become destabilized. It is at this point that tremors ensue. Of note, areas that are known for people that "Pour the Coal" when having sex are most at risk for earthquakes of this nature.
Man, I was poring the coal and Valentines Day so hard that a 4.4 Valentine's Day Earthquake happened!
