Fifthmas
A holiday celebrated every December 5th in which it is required that you consume at least one fifth of alcohol. It celebrates the end of the prohibition on December 5, 1933 and is a last hoorah before final exams start. Started at Hope College in 2011 it has spread like wildfire to all parts of the world.
