Dining In, formal service member only event that begins with solemn readings and toasts and ends up a drunken free for all.
Grog is made from a long list of specific ingredients. That sock is is filled with spices, to represent the dust from soldiers long marches.
My ANCOC classes were required to plan and host one the night before graduation. We would keep a bottle of "seed grog" from year to year to start it off.
President of the Mess fines people for breaking the Rules of the Mess, or for any reason whatsoever. Fines can be money, a portion of grog, a dance, a witticism or a poem, etc.
We would end with a tribute to our Fallen Comrades, small mini-ceremony that ends with Taps. I'll get a speck of dust in my eyes every time. No crying.
Best time ever.
"Mr. Vice, SFC David E. Valentine, 3-183 Regiment, Point of order!"
