Friends don’t let friends drink alone.  A shotski is a popular instrument used for the drinking of hard liquor and has the reputation of stealing the party.  

Quite simply, it is a ski with a number of removable shot glasses affixed to it.  Participants simultaneously tilt the ski and all take a shot at the same time.  Shotskis are just as common outside the realm of winter sports as they are around ski resorts.  You don’t need snow to have a drink.
