I was recently on a school skiing trip to Austriaand during a late night Puschkin drinking session was informed of the minute game by Max our barman.
One of many simple Drinking Games like the Withnail and I Drinking Game or I have never or Gooday Bruce. This simply involves everyone present to take one shot every minute. If you have to leave (for example to go to the toilet, throw up etc) you must be back within the minute or else you take an extra penalty shot in addition to the one you have missed. Apparently the 1st 10 minutes are fine but after half an hour things get hazy.
