National Men's Holiday on Dec 27th. This celebration time is when friends (men) get together and celelbrate all things poon. Original design was to fill the void between Christmas and New Years.

In Canada the tradition is to gather in the morning and start the comsumption of beer - followed by visiting all the nudie bars and sex stores until it is time to pass out.

This is now in it's 9th year in Canada, started in Richmond, BC.
