Enter online matchmaking, this can be played as a team or by yourself. You must enter matchmaking as random. Once you load into the game the first thing you have to do is select one unit to build and only that unit for the entire game. (This does not include your workers)
Every time you lose an engagement you must take a drink. If you destroy destructible rocks or expand you must take a drink. For every upgrade completed you must take a shot. If you are playing in a team the person out of the game first must finish their drink.
