Well, first off, this wasn't done by my fraternity. I first witnessed the anal chug at the wedding of a fraternity brother who had also invited high school friends. We were drinking too much at a very nice NJ country club. The college friends were standing on the deck, dipping Copenhagen, and spitting onto the green below. The high school friends were engaged in the anal chug. Basically, one guy lies on the ground on his back with mouth open. Another guy opens a cold beverage. The third guy drops his pants and pulls up shirt slightly. The beer (or other beverage) is poured over the small of the back so that it drips through the butt crack and pours into the waiting man's mouth. As gross as this may sound, a year after my first encounter with this phenomenon, I saw something even more foul . . . Anal chug with egg nog. "Crack Shots" have always been a rush week deal or used as collateral for betting. I've never heard of anyone lining up to do it voluntarily. If you've been served a Crack Shot Cement Mixer 3 Wise men Mat Shot Scooby Snack etc This is not a 'good" thing - this is a "hey, I justed turned 21" thing
