In college in the 1980s we would buy a new plastic garbage can from K-Mart and make the punch for the ladies.  Gallons of grain alcohol, and dozens of 2-liter bottles of any sweet cola.  A dozen or so sliced lemons, limes, oranges floating on top.  Throw in bags of ice, and stir with a wooden boat paddle.  And lots of red Solo cups. Was always a hit, always emptied by the ladies.     On a Student Government retreat we didn't have an opportunity to get a garbage can, so we used a bathtub in one of the hotel rooms and used an ice bucket as a measuring/stirring device. And, once again, before midnight the ladies had emptied it while the guys tried to figure out a way to dispose of dozens of empty beer bottles/cans without our chaperones finding out the next day.
