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.
